Eaton M22 Series key-operated selector switches are designed to be operated by a key to select the desired position or mode of operation, as well as provide an added layer of security by preventing unauthorised access. Their compact design allows easy conversion from momentary to maintained operation and vice versa for quick accessibility in demanding applications. Eaton M22 Selector switches consist of a rotating cam with ridges and flats, allowing the plunger to actuate independently in three positions. They offer NEMA and IP66 protection ratings to provide a level of protection against dust, water, and other potentially damaging elements.
