WARNING: To avoid electrical shock and/or unintended operation of equipment, disconnect all power to the limit
switch and the controlled equipment before proceeding with any repair or adjustment of the limit
switch.
Overview
Limit Switches are used in electrical control systems to sense
position. They are actuated by the predetermined motion of a
cam, machine component, or piece part. This mechanical
motion is then converted to an electrical signal through the
actuation of a set of contacts. These signals can be used in
the control circuits of solenoids, control relays, and motor
starters to control the operation of conveyors, hoists,
elevators, machine tools, etc. They are not to be used to
directly control a motor.

Mounting
Units should be mounted using the mounting holes provided.
These mounting holes are counter boarded to help contain
the bolt heads. The use of M5 Cap Screws, (Hex head), and
washers is recommended. Mounting bolts should be torqued
to a value between 4.90 and 5.88 Nm. These units have been
designed to enable gang mounting. In the case of ganged
mounting, the installer should fit the convex part of the gang
mount guide into the concave guide of the adjacent switch. A
maximum of six switches may be ganged. Special units that
have been designed for panel mounting will be provided with
a threaded head. These switches will also have washers and
a mounting nut included with the switch.
