CLW2-32 32A Modular Cam Switches

Description

CLW2-32 modular cam switches have a conventional thermal-current rating of 32A. Their rotary contact programs cover on/off switching, changeover, instrument selection and motor-control applications. Conventional, label, illuminated, G2-handle and panel-key arrangements provide distinct operating and mounting choices.

Choose the position program, contact schedule, section count, handle and panel print together. Standard detent versions support up to nine sections; spring-return and illuminated versions support up to eight. Eight or fewer sections are generally recommended, with six or fewer recommended for the illuminated D version. Standard indexing steps are 45°, 60° and 90°.

Position and Return Programs

The first position-code 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. For unrestricted 360° rotation, the ending letter repeats the starting letter: 45° gives eight positions, 60° gives six and 90° gives four. Contact logic and section count can restrict available travel.

Mounting and Dimensions

Dimensions below are in mm; n is the number of contact sections. The contact-block pitch is 12.8mm. All illustrated versions use 1–4mm panels, four Ø4.5 fixing holes on a 48±0.20 square and a central Ø10 opening.

On/Off and Changeover Contact Programs

Each section adds the two terminal pairs shown below. For a chosen section count, include every row from section 1 through that count. On/off programs open all contacts at 0 and close both pair groups at 1. Changeover closes the first group at position 1 and the second at position 2; center-off adds an all-open position 0 between them.

Three-, Four- and Five-Position Programs

For each program, use only terminal pairs within the stated range. Each fitted pair closes at the position in the contact map and stays open at other positions. Keep the links in the corresponding wiring diagram. The ten-section references exceed the standard nine-section detent limit. Their illustrated schedules cover only pairs 1–2 through 35–36 and do not specify additional contacts.

Print codes identify wording and physical layout. The English equivalents below preserve the label meanings; drawings show their positions and return arrows. Special printing uses P; omission retains the contact program's standard printing.

Custom Contact Specification and Small Loads

Specify thermal current, mechanical function, handle, panel wording, operating directions and the open/closed state of each terminal pair at each position. The worksheet provides nine sections, with pairs 1–2 through 35–36; the selected mechanism's section limit still applies.

CLW2-32 nine-section custom contact worksheet
Worksheet for a complete operating and contact sequence.

The standard minimum applicable load is 24VDC, 10mA. Smaller signals require an appropriate small-load contact configuration. Contacts used on 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.

Cam switch small-load and standard-load operating regions
Small-load reference regions, including the illustrated 5mW and 800mW boundaries.

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.
