Description

This control switch has been designed to solve the variety of problems encountered in chemical and petrochemical plants and on explosionproofed electrical machinery. Four switch contacts as opening and closing elements in different permutations permit a variety of functions. The opener has a positive break operation. The switch actuator offers latched and momentary-contact positions with different switch positions.

The control switch can be installed quickly and directly into double or triple ComEx enclosures, or in combination with other command devices in control units.
