Cam switches are electric rotary multi-circuit switches adapted to switch on and off currents. Cam switches are used in housings of low voltage electrical installations, especially as circuit breakers, disconnectors, switches and control switches. Cam switches can be installed indoors (pollution degree 3 - industrial use) at -40...+70°C (ŁK40, 63) and -25...+70°C (ŁK15).
