Selector Switch Operator · 3-Position Momentary · 22.5 mm Silver Bezel · Eaton M22-WK3

What this product is for

This 22.5 mm selector switch operator is used on industrial control panels, operator stations, and machine interfaces where an operator needs to select between three positions with momentary spring-return action.

Use for

Use for machinery control, automation panels, process stations, and logic control equipment. It is commonly paired with compatible M22 contact blocks to build a complete selector switch assembly.

Avoid for

Avoid using this as a complete switch assembly on its own if contacts are required, since this SKU is an operator only. Avoid illuminated applications where visual status indication is needed at the actuator.

Best for

Best for panel builders and maintenance electricians standardizing on Eaton RMQ-Titan / M22 22.5 mm pilot devices and needing a non-illuminated 3-position selector with a silver front bezel.

Installed in

Installed in a 22.5 mm panel cutout. Front diameter is approximately 29.7 mm (1.17 in), and overall product depth is about 46 mm (1.81 in).

Why this product exists

This operator provides manual three-position control in a compact 22.5 mm format for industrial panels. The momentary spring-return function is useful where temporary command input is needed rather than a latched selector position.

Compared with similar products

Compared with maintained selector operators, this model is intended for temporary actuation. Compared with illuminated operators, it does not provide local visual indication but simplifies panel layouts where indication is handled elsewhere. As a rule of thumb, selector operators like this are commonly chosen for jog, inching, raise-lower, or open-close commands, but actual suitability depends on the contact arrangement and control logic used.

Actual performance depends on contact blocks, wiring, panel design, and local electrical code.
