MOUNTING

LZ may be mounted without unplugging the

body from the base receptacle. Use two M5 or

#10 screws that are at least 32mm (1.25 in.)

long. A third mounting screw may be used by

removing the knockout in the lower right

corner. Refer to Figure 1.

WIRING

Up to 3mm or AWG12 wire may be used for

wiring to the self-lifting pressure plate-type

screw terminals. Maximum width of spade

connectors or diameter of ring connectors is

8mm (.312 in.). A ground terminal, which is

colored green for easy identification, also has

self-lifting pressure plate-type construction

(refer to Figure 1.).

POSITIONING LEVER OF ROTARY TYPE

The lever on rotary switches is adjustable to

any angular position through 360°. Levers

are reversible, they can also be shifted axially

through approximately 3,2mm (.125 in.) on

the shaft. To adjust, or to assemble to switch,

loosen the screw with a 9/64 hexagon key

wrench, move the lever to the desired posi-

tion, and securely tighten the screw. The

lever should be tightened until the "teller tab"

can no longer be moved by hand. Hex key

wrenches are provided in adjusting tool set

LSZ4005.

While we provide application assistance on

MICRO SWITCH products, personally and

through our literature, it is up to the customer

to determine the suitability of the product in

his application.

SIDE ROTARY TYPE

SIDE LEVER BRACKET TYPE

POSITIONING THE SIDE LEVER BRACKET

CHANGING ACTUATION DIRECTION

REVERSING THE ROLLER LEVER ARM

ON ROTARY TYPE

The side lever bracket can be placed in any of

four positions. When combined with the four

possible head positions, this makes for 16

possible positions for this type. Remove the

lever with a 5/32 inch hexagon key wrench.

Loosen three captive bracket screws, place

the bracket in the desired position, and

securely tighten the screws (refer to Figure

Roller arms may be reversed to face the roller

to the inside or outside of the arm (refer to

Figure 7). It is recommended that the lever of

side lever bracket forms be adjusted within

the parameters shown in Figure 7. Use a 5/32

hexagon key wrench.

Rotary switches may be adjusted to operate

clockwise, counterclockwise, or both. Instruc-

tions are cast into the head (Figure 4). Follow

these steps:

1. Loosen the four captive head screws and

remove head from switch housing.

2. Switches are assembled with the plunger

set for both way operation. (See drawing

Figure 4.)

6).

Both way actuation: plunger point in

twelve o'clock position (towards the

actuator).

To change mode of operation pull the

spring loaded plunger outward with pli-

ers to the stop. With plunger, pulled turn

the point in the direction of operation

required.

Clockwise actuation only: turn clock-

wise to three o'clock position.

Counterclockwise actuation only: turn

counterclockwise to nine o'clock posi-

tion.

3. Release plunger, it will snap into the head

into a locked position.

4. Replace operating head on switch hous-

ing and securely tighten screws.

5 . Check for desired operation by actuating

switch and listening for "click".

HEX HEAD SCREWS

If you prefer to loosen and tighten the lever

with a pliers or a screwdriver, a packet of 50

hex head screws, with screwdriver slot, is

a v a i l a b l e s e p a r a t e l y ( c a t a l o g l i s t i n g

15PA164-LS) to replace the allen head screw

furnished with the lever.

WOBBLE STICK ACTUATOR TYPE

REPLACING THE WOBBLE STICK

To remove a wobble stick, firmly grasp the

wobble stick with a pair of pliers at the base of

the wobble stick. (Figure 8, View A.) Turn the

wobble stick counterclockwise to unscrew it.

Adjusting tool set LSZ4005 consists of one

special 3/32 inch open wrench and necessary

hexagon key wrenches to adjust all types of

levers.

To attach a wobble stick, start threading the

actuator to the head by hand. Then firmly

grasp the wobble stick with a pair of pliers as

shown in Figure 8, View B. Turn the wobble

stick clockwise to within 1/8 inch of the end of

the threads.
