Rotary switches

The development of the Blue Line rotary switch and motor starter product ranges is based on more than hundred years experience by Kraus & Naimer in the design and manufacture of electrical switchgear. Kraus & Naimer pioneered the introduction of the cam operated rotary switch and continues to be recognized as the world leader in that product field.

The C-series switch represents the classic cam switch by Kraus & Naimer. With specific models for all current ratings it offers an ideal solution for a wide variety of applications. 

The CA-series with finger proof terminals from 10 A to 32 A is ideally suited for many standard applications where industrial controls, instrumentation and electric motors are involved. For low-voltage applications down to switching of electronic signals the CA4 and CA4-1 are offered. The CA4-1 has gold-plated contacts and guarantees reliable switching, even under adverse, aggressive environmental conditions. Cam switches of the CG, CH and CHR-series are designed for universal applications.

Different contact designs, contact materials and terminals allow the use the C-Series switches in accordance with IEC 60947-3, EN 60947-3, VDE 0660 part 107, UL and cUL (cUR)

Fingerproof terminals, accessible either horizontally or vertically, captive Philips screws and integrated screwdriver guides designed for the use of motorized screwdrivers are some clear practical advantages of this series.
