TERMINATION

Termination is specified in the order

guides. Leadwires are generally six feet

long, and of the gage and Military Specifi-

cations noted in the order guides.

MOUNTING

Plunger actuator switches mount through

⁄8 inch or 15⁄32 inch diameter holes. Lock

washer, keyed washer, and wire lock hex-

agon mounting nuts lock the switches in

their mounting holes.

Rotary actuator switches mount through

15/32 inch diameter holes. A lock washer

wire lock hexagon nut and locating pins

on the top of the housing prevent switch

rotation.

OPERATION

Plunger Actuators

For in-line actuation. An ice scraper ring

cleans the actuator with each operation.

Ball Bearing Plunger Actuator

For random direction operation. An ice

scraper ring cleans the actuator with each

operation. For further information, con-

tact your nearest MICRO SWITCH Sales

Office.

Roller Plunger Actuators

For cam and slide actuation not to exceed

° rise. Roller adjusts laterally in 45° in-

crements. An ice scraper ring cleans the

actuator with each operation.

Rotary Linkage Lever Actuator

A threaded rod attaches to the rotary lever

for positive actuation. The rotary lever op-

erates in either direction and adjusts lat-

erally to any position through 360

°. The

threaded rod pivots in two planes. The ac-

tuator has no spring return, but is con-

trolled directly by the movement of the ac-

tuating device.

Rotary Roller Lever Actuator

For cam and slide actuation with more

than a 30

° rise. A spring returned mecha-

nism, this actuator is available in clock-

wise and counterclockwise operation de-

signs. The actuator adjusts laterally to

any position through 360

°. The roller is

laminated phenolic.
