Eaton M22-WR — M22 2-Position Selector Switch Maintained

2-position maintained selector switch for Eaton M22 series. 22.5mm cutout, IP67 front. Standard knob handle.

Common Applications

Two-position maintained selector switch from the Eaton M22 series. Used for hand/auto mode selection on pump stations, local/remote switching on motor control centers, and on/off functions where a toggle-style action is preferred over a push button. The maintained action stays in the selected position, giving the operator a visual reference of the current mode. IP67 front face handles washdown and dusty environments. The selector pairs with M22-series contact blocks — typically one 1NO block per position wired to PLC discrete inputs for mode selection logic.
