TE Connectivity 164EL22 Pushbutton Switch Momentary

TE Connectivity's 164EL22 ALCOSWITCH is a round, illuminated pushbutton switch intended for panel mounting on compact 16 mm cutouts. The device is a momentary pushbutton with two normally open and two normally closed contacts (DPDT), enabling two circuits to be switched in a momentary fashion when pressed. As part of the ALCOSWITCH family, the 164EL22 integrates illumination for operator feedback, making it suitable for control panels, instrument housings, and equipment where a brief push-to-momentary input is required. The 164EL series designation indicates a 16 mm diameter footprint and round actuator; its electrical action is momentary, returning to the resting state when released, with the ability to drive simple control sequences, alarms, or interlock logic. Its compact form and standard TE Connectivity footprint support straightforward replacement in compatible assemblies and a range of panel-mounted applications in industrial automation, machinery controls, and user interfaces where reliable tactile feedback and visual indication are beneficial.
