Rotary Cam Switch is a type of electrical switch operated by rotation, and gets the name from it’s internal operating principle.
If named by the function, then you can call it ON-OFF Switch, Disconnect Switch, Main Switch and Control Switch for ON-OFF function. Or Start-Delta Switch, Motor Switch for Motor Circuit. Changeover Switch, Selector Switch and Multi-Step Switch for conventional circuit switching. Voltmeter Switch and Ammeter Switch for measurement.
Normally, there are 3 main mounting ways of the switch:
- Rear Panel Mounting (22mm sigle hole, 28mm or 30mm double hole, 36x36mm or 48x48mm or 68x68mm four holes);
- Base Mounting (35mm DIN-rail, 36x36mm or 48x48mm or 68x68mm four holes and door interlock with base mounting);
- Enclosure Mounting. (Mounting size according to different manufacturers)
