CR115B

Precision Snap-Acting Limit Switches

15 Amperes Continuous

AC/DC

Application

Designed for rugged industrial use in a small space and where

highly repetitive operation is desired. These highly accurate

switches require only a small amount of plunger travel to actuate.

One- and two-pole forms are available.

The basic switch is equipped with a button-type operator.

Plunger-type forms are available for mounting behind the panel

with only the button protruding. Roller lever forms are available

for applications requiring a transfer of the axis of motion or for

detection of objects passing the switch.

Typical applications include controlling solenoids, opening and

closing valves, and controlling small horsepower motors.

Features

—Wear-resistant nylon button: retains perfect alignment with

operating parts.

—Rugged molded enclosure: resists arc-over and shock.

—Operating head: available in button-, plunger-, and roller-lever

types; plunger operator also available as accessory kit.
