ESSEN momentary contact Limit Switches are manufactured to meet requirements of switching auxiliary and control circuits at voltages upto 500 Volts and currents upto 10 amperes.
Each switch is having one pair of normally open and one pair of normally closed contacts. The contacts are of silver, designed for very low contact resistance and long life. All current carrying parts of the switches are thick silver plated. The contact springs are robust and the switch can be operated at frequencies as high as 3000 switching cycles per hour.
These switches are available in open execution or in Aluminium alloy diecast housing. They can be operated by an actuating-bar cam or any other suitable means. Switches with roller lever can be operated from 4 directions in steps of 90o. The actuating position of the roller remains fixed.
Snap action limit switches are specially designed for extremely low operating speeds. To prevent ingress of dust particles, switch elements with a cover are available.
