This item is a PM162H22E/R/12V/S 16 mm diameter momentary push button switch with 2NO2NC contacts, supplied as a single piece in black. It is described as a momentary type. Key benefits Flexible control: the 2NO2NC contact arrangement lets you run two normally open and two normally closed circuits from a single push button, enabling versatile control logic in a compact package. Quick, momentary action: designed for momentary operation, providing immediate actuation and quick reset when released, suitable for start/stop or reset functions. Compact 16 mm form factor: fits standard 16 mm panel cutouts, enabling easy integration into control panels, consoles, and equipment enclosures. Clean black finish: a neutral black appearance that blends with most panel designs and UI layouts. Simple integration: the model PM162H22E/R/12V/S aligns with common 12 V system architectures, simplifying wiring and compatibility in many applications. Product attributes Model and variant: PM162H22E/R/12V/S (Black, Momentary type, 24V reference in the label) Size: 16 mm panel diameter Contact configuration: 2 normally open (NO) and 2 normally closed (NC) Operation: Momentary (nonlatching) Voltage context: 12 V (as indicated by the model designation) Color/finish: Black Quantity per : 1 piece Typical applications Start/stop control for machinery or conveyor systems where a momentary push is required to energize or disengage a circuit. Panel or control console inputs where two circuits need simultaneous or complementary signaling (NO and NC) from a single switch. Test rigs and lab setups that rely on momentary actuation to trigger signals or power circuits during testing or calibration.
