kraus-nmaier Cam switches of the CG, CH and CHR-series are designed for universal application and may ideally be used for control switches, instrumentation switches and motor control switches. Different contact designs, contact materials and terminals allow the use as well as in electronic circuitry and in aggressive environments in accordance with IEC 60947-3, EN 60947-3, VDE 0660 part 107, UL and cUL (cUR). The stage is the basis for all switches and can be supplied with a maximum of 2 contacts.
All switches of this series are supplied with open terminals which are accessible while the switch is installed. The terminals are protected against accidental finger contact according to EN 50274, VDE 0660 part 514 and DGUV V3. Captive plus-minus terminal screws and integrated screwdriver guides facilitate wiring.
Due to the particular arrangement of the terminals of the CG switches, it is possible to install the switches closely, side by side, or to mount them directly at the cable trays. The contact terminal numbers are easy to read, even if the switch is installed. The captive plus-minus screws of the CH and CHR-series are located about 90° apart from the terminal direction.
This allows for connecting wires without any interference with the terminal screws. For connection with ring type terminals the CHR-series were designed.
The switches are supplied with large open terminals. This allows for connection without removing the screws.
