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.).

Catalog Listing
To order replacement levers,
order the same part number as
that which is metal stamped on

plane by locating the head as outlined under
Actuator Head.
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.

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.
