FM  
SERIES  
The FM series foot switches are ideal for light or  
medium duty applications and especially medical  
applications. The compact, sturdy but small, ABS  
housing is designed to meet all the different contact and  
switch insert configurations.  
This series has many features, such as maintained and  
two stage momentary contacts, two different colors, and  
two protection levels. It also offers a variety of flexibility  
and alternatives already in the standard versions. The  
wide range of options include:  
• Protection levels IP 68 (Medical versions  
IEC 601-1 certified)  
• Especially designed gold plated  
contacts for low current  
• High current switch inserts  
• Different cable entries/strain reliefs  
• Other cable versions, with shield  
• Custom colors for the guard,  
custom connectors.  
The standard and optional features together provide  
various application possibilities:  
Foot switches are typically used when hands-free  
operation is required or when the hands are needed to  
perform a separate task while the machine or device  
must be started or stopped,  
or the machine requires manipulation in other ways.  
Application examples would be:  
• Conveyor belt in supermarket  
• Sewing machine in textile factory  
• Control of dentistry tools  
• Operation of logical or digital signals  
Warning  
Please see page 25 in reference to the warning that  
applies to every application.

PCFS-3M  
SERIES  
Altechʼs new low cost foot switch is ideal for any light to  
medium duty application. The PCFS-3M has an  
electrical rating of 10A (1/2HP)/125V AC, it can serve as  
a foot operated on/off switch for a wide range of motor  
driven and electrical devices.  
Characteristics:  
The virtually indestructible steel housing meets even  
more challenging demands of every day applications.  
The steel guard comes standard in red or orange and  
provides an affordable “safeguarding” of the foot switch.  
The guard is interchangeable with the FM1 series foot  
switch which makes this configuration a perfect fit for  
more cost sensitive applications.  
Application Examples:  
• Operation of logic signals  
• Coil winding machines  
• Photo lab equipment  
• Sewing machines  
• Packaging equipment  
• Conveyor belts

FL  
SERIES  
The FL series foot switches are appropriate for heavy  
duty applications in hazardous and demanding  
environments. The foot switch with the Polyamide 6.6  
housing shows the same sturdy body as the FS series,  
but with the advantage of resistance against water, oil,  
and certain acids and chemicals, which enables a  
longer life expectancy. The foot guard consists  
of die cast aluminum, to sustain all safety requirements.  
The FL series offers considerable flexibility with the  
combination of slow make-break and snap action switch  
inserts, with the contact types momentary, maintained  
and two stage  
momentary and the choice of different  
potentiometer values. Human safety and  
machine protection can be provided by adding  
of Anti-Trip lever and foot guard. These items prevent  
the foot switch from accidentally  
actuating the machine function. Different strain reliefs,  
cables, connectors and custom colors  
are also available.  
The main applications of this non-corrosive foot switch  
are “wet” industrial environments, drilling processes, and  
in the food industry, where the environment has to be  
cleaned regularly with cleaning detergent.  
Warning

Ergonomic  
FS3+1  
Foot switches for medical applications require unique designs for safety, reliability and hygiene. Almost every foot switch is a  
custom product. Altech is a leader in designing these medical foot switches that combine the unique requirements needed for  
these demanding applications. Altech’s design department has designed foot switches to meet a doctor’s preferences such as  
an actuation force from 0.5 lbs. to 50 lbs. Sometimes it is as simple as a cable length change, a totally different cable, or a  
special connector. Here are some of the existing designs:  
• FM1 was molded using a special white ABS material  
• FM2 required an aluminum base plate with blue and yellow pedal covers  
• FM3 is ergonomically designed for an ENT doctor  
• FS3+1 was mounted on an aluminum plate, which connects to an FS1 with 1 cable exit  
The foot switch on the right shows an  
innovative concept created by our  
design department. This takes the  
foot switch to a totally different level  
incorporating new ideas and blending  
them into modern equipment designs.  
Altech Corp can design and  
manufacture a foot switch to meet  
needs. Give us an opportunity to  
quote on your requirements!

FS  
SERIES  
The heavy duty, medium size FS series foot switches are  
primarily used in industrial and medical applications. Due  
to the sturdy design of the die cast aluminum housing,  
the foot switch is an exceptional value for strict  
environments. This compact design offers a lot of  
versatility:  
• Every combination of slow make-break and snap  
action switch inserts with momentary, maintained and  
two stage momentary contact types are possible.  
Different potentiometer values are also available.  
• Additional safety features like a foot guard, Anti-Trip  
lever and especially two safety foot switch versions  
complete this line.  
• The optional medical versions and explosion  
protected foot switches meet the requirements of  
either IEC 601-1 or EEX d ||C T6, and come with  
appropriate strain relief and 3 meter (10 ft.) cable.  
• The foot switch can be customized with a wide range  
of options, including cables, connectors, colors, and  
foot rests.  
The typical industrial applications include:  
• ironing machines  
• construction machinery  
• sand blasting machines  
• bending machines  
• machine tools  
• medical equipment

WARNING for General Applications  
The use of foot switches on machines, which do not have “point of operation” and “pinch point”  
protection can cause serious injuries to the operator!  
The point of operation and pinch point guarding devices should be properly installed before a foot switch  
is used. The foot controls should be utilized so that it is impossible for the operatorʼs hands  
and fingers to remain within the point of operation during the machine cycle.  
Point of operation - The point or area of the machine or the equipment where the work piece or  
material is positioned and work is being performed during any process such as forming, cutting, welding,  
punching, shearing, assembling, riveting, etc.  
Pinch point - Any point at which it is possible for a portion of the body to be caught and injured  
between moving machine or equipment or work piece parts.  
Additional WARNING for Medical Applications  
Medical environments have high demands for safety and hygiene. The use of inadequate foot  
switches can cause serious injuries to the user and patient! The Altech/ASA foot switches meet  
the requirements of IEC 60601-1 for medical electrical equipment.

FEATURES APPLICABLE TO THE FS SERIES  
Safety Foot Switch  
To prevent accidents, Altech/ASA has included a special safety foot switch in its line.  
The concept is based on an extensive survey, which indicated that, in case of an  
accident the user depresses the foot pedal even harder instead of releasing the pedal.  
This special safety foot switch is designed to compensate for this emergency situation,  
by breaking electrical contact when the pedal is completely depressed. It has modified,  
two stage momentary contact types, with a manual reset button.  
Safety Foot Switch Functions  
Step 1: The pedal is not depressed. The contacts are  
open. The machine is turned off.  
“OFF”  
“ON”  
Step 2: To start the machine, the pedal must be  
depressed until the “pressure point”, where resistance  
is noticeable.  
Step 3: In an emergency, if the pedal is depressed  
beyond the pressure point, the machine will stop.  
Beyond the pressure point, the contacts are locked in the  
“OFF” - Position. The machine cannot operate at this  
time.  
“EMERGENCY -  
OFF”  
Note: The machine can also be stopped, by releasing  
the pedal instead of depressing harder. (Back to Step 1)  
Step 4: The push button on the side of the foot switch  
must be pushed by hand to enable the foot switch to  
start the machine function again.  
“RESET”  
“ON”  
Step 5: Return to condition described in Step 2.  
The safety foot switch is available in the one and two pedal heavy duty with guard versions.  
See pages 20 and 22 for more information on the FS1 ... U and FS2 ... U Series.

FEATURES APPLICABLE TO THE FL AND FS SERIES *  
Foot Guards  
Foot Rests  
Foot Guards are used to  
prevent accidentally actuating  
the foot switch by falling  
objects such as parts and  
tools.  
Ergonomically designed foot  
rests help reduce fatigue  
that may set in after  
operating a foot switch for  
an extended period of time.  
Foot rests are available on  
the one pedal versions of  
the FL and FS series, with or  
without a guard.  
Most European accident  
prevention standards such  
as the German Berufsgenos-  
senschaft (BG) (similar  
function to OSHA) require foot  
guards for many applications. In addition there is a  
special space under the guard, where certain devices  
such as, emergency off switches and contactors can be  
mounted.  
Potentiometers  
Foot switches can be ordered with built-in potentiometers  
to change speed, etc. Typical applications include:  
• Coil Winding Machines • Pumps  
Anti-Trip Lever Mechanism  
• Machine Tools  
• Sewing Machines  
• Welding Machines  
(Prevents the pedal from accidental actuation)  
• Medical Facilities  
Step 1: To depress the  
pedal, the Anti-Trip  
lever must be pushed  
forward. Otherwise, a  
spring loaded  
Function: In the “OFF” position the potentiometer is at  
“zero”. A microswitch connected in series to the  
potentiometer will only provide a voltage to the  
potentiometer once the foot switch has been activated.  
The standard resistance of  
the potentiometer foot switch  
is 10k Ohm which provides a  
proportional signal depending  
on the position of the foot  
pedal (Resistances of  
mechanism holds the  
lever in position.  
Step 2: After the lever  
is pushed forward, the  
pedal can be easily  
depressed.  
100 Ohm to 20k Ohm are  
also available).  
Potentiometers are available  
for the FL and  
FS Series.  
Two Stage Function  
Step 3: Immediately  
after releasing the  
pedal, the spring  
The following describes the mechanical operation of two  
momentary contact types:  
loaded mechanism  
brings the lever back to  
its starting position.  
Stage 1: To activate the first  
momentary contact, depress  
the pedal until resistance is  
noticeable.  
Stage 2: To activate the  
second momentary contact,  
press the pedal beyond the  
resistance point.  
The maximum human safety and  
machine protection is provided by the  
combination of Anti-Trip lever  
mechanism and Foot Guards!  
Both functions are now turned  
on. By releasing the pedal, the functions will be turned  
off in reversed direction.  
* The two stage function is applicable to all foot switches.
