ActiveM22 2-Position Selector Switch
2-position maintained selector switch for Eaton M22 series. 22.5mm cutout, IP67 front, with 1NO contact.
Common Applications
Three-position selector switch (left-center-right) with maintained action in all positions. Used for hand/off/auto control on pump stations, HVAC fan speed selection (low/medium/high), and conveyor direction control (reverse/stop/forward). The black knob with white position indicator is easy to read at a glance. Each position actuates different contact blocks mounted on the rear — typically wired to PLC discrete inputs for mode selection logic.
