Selector Switch - 3-Position, Momentary, 2NO, Silver Bezel · · Eaton C22-WK3-K20

What this product is for

This 22.5 mm selector switch is used for operator control on industrial and commercial panels. It provides 3-position momentary switching with 2 normally open contacts for control circuits that require temporary actuation.

Use for

Use for machinery controls, motor control stations, process panels, and OEM equipment where a maintained contact is not required. Typical applications include jog control, directional commands, and spring-return operator input.

Avoid for

Avoid using this device where maintained position is required, where illumination is needed for operator indication, or where a different contact arrangement is specified by the control schematic.

Best for

Best for electricians, panel builders, and maintenance teams standardizing on Eaton 22.5 mm control devices and needing a compact selector switch with silver bezel styling and built-in contacts.

Installed in

Installed in control panel doors, operator stations, machinery enclosures, and commercial or industrial equipment with a 22.5 mm mounting provision. Overall device depth is approximately 1.17 in (30 mm) and height is approximately 2.83 in (72 mm).

Why this product exists

This selector switch gives panel builders a compact way to add temporary multi-position control without separate modular contact assembly. For many control circuits, momentary action helps prevent unintended sustained operation. Actual circuit behaviour depends on wiring design, relay logic, and local electrical code.

Compared with similar products

Compared with maintained selector switches, this model is intended for spring-return operation rather than staying in position. Compared with illuminated operators, it does not provide visual status indication. Compared with modular devices, the C22 compact format can simplify selection where an assembled operator with built-in contacts is preferred.
