M22M-WS3-MS4 - 

Eaton’s M22 selector switch line offers an almost endless variety of options in maintained/momentary, key removal and illuminated devices. The coding adapters used for maintained/
momentary and key removal positions make the M22 stand out from competitive devices. By simply adding or removing a coding adapter from inside the operator, the end-user can change the function of the button. Operator options include standard knob, rotary head, illuminated and keyed versions. As with all operators, they can be ordered as modular components or as part of complete switch assemblies to meet application specific requirements.
