CLW2-63 cam switches provide modular rotary switching with a 63A conventional thermal-current rating. Select an on/off, changeover, instrument-selector or motor-control contact program, together with its operating positions, handle, mechanical function and panel wording.
Standard detent versions support up to eight contact sections; spring-return and illuminated versions support up to seven. The mounting arrangements recommend six or fewer sections. Indexing steps are 45°, 60° and 90°. Conventional, label, illuminated, G2-handle and panel-key versions have different front plates and rear-depth requirements.

The first character is 4 for 45°, 6 for 60° or 9 for 90°. The next two letters identify starting and ending positions clockwise on the matching circle. A is the 0° reference; O is a position letter. Unrestricted 360° rotation repeats the start letter as the end letter: eight positions at 45°, six at 60° or four at 90°. Contact logic and section count can restrict travel.

Specify thermal current, mechanical function, handle code, panel wording, operating directions and the contact state of every required pair at each position. The worksheet has eight sections, with pairs 1–2 through 31–32; the chosen mechanism's section limit still applies.
The standard minimum applicable load is 24VDC, 10mA. Smaller signals require an appropriate small-load contact configuration. Contacts used for general loads should not subsequently be reused for smaller signals, because surface changes can reduce low-current reliability. Use suitable CR suppression and contact protection where bounce, noise or pulse currents affect the circuit.
These switches are intended for industrial controls. High-reliability infrastructure, safety-critical transport or medical systems, severe outdoor or contaminated environments, fire or explosion hazards, military uses and large engineering projects require a specifically designed and expressly confirmed configuration.
