The rotary cam switch is intended for multiple switching operations in main as well as in auxiliary circuits:
• Rotary Cam Switch as motor switches they are designed for direct-online starting and stopping of single-phase and three-phase motors. They also come out as star-delta switches, reversing switches, pole-change over motor switches
• in auxiliary circuits they are assembled in compliance with the switching program according to preference; switches for control, signalling and measuring circuits.
• switches, selector switches and step switches e.g. for transformers and welding apparatuses
• group switches e.g. for switching operations of resistors and heaters
• control switch with automatic return
The rotary cam switches can have 12 control positions and 12 switching elements (24 contacts) maximum and can be made with turning angle of 30˚, 45˚, 60˚ and 90˚.
