Selector switch operator 4-position maintained non-illuminated silver bezel Eaton M22-WRK4
22.5 mm maintained selector switch operator for panel control stations, with 4 positions, non-illuminated knob, and silver bezel. Commonly used in industrial control panels and machinery HMIs where a selected position must stay in place until changed.
What this product is for
This selector switch operator is used in 22.5 mm panel openings for machine control, automation panels, and operator stations where a maintained 4-position selection is required.
Use for
Use for industrial and commercial control panels, OEM machinery, process control stations, and equipment interfaces that need a non-illuminated rotary selector with four fixed positions.
Avoid for
Avoid where illuminated indication is required at the operator, or where a spring-return or key-operated selector is needed instead of a maintained knob operator.
Best for
Best for electricians and panel builders standardizing on Eaton M22 22.5 mm control devices and needing a silver bezel operator for multi-step mode or function selection.
Installed in
Installed in control enclosures, machine panels, MCC-style operator stations, and industrial cabinets. The operator fits a 22.5 mm mounting size, approximately 0.89 in.
Why this product exists
It provides a maintained 4-position manual input so the selected operating mode remains in place until intentionally changed. This is commonly used for staged control, mode selection, or multi-function equipment commands.
Compared with similar products
Compared with 2-position or 3-position selector operators, this 4-position version gives more control states from one panel opening. Compared with illuminated operators, it is suited to applications where indication is handled elsewhere on the panel. Typical buying check: confirm the required contact blocks, legend plate, and position marking for the intended control scheme.
