Product Description: SPST Normally Closed Detector Switch – Vertical Through Hole

This precision detector switch is engineered for reliable status sensing in compact electronic assemblies. Featuring a Single-Pole, Single-Throw (SPST) circuit configuration with a Normally Closed (NC) contact arrangement, the switch maintains electrical continuity in its resting state. When actuated, the circuit opens, providing a clear signal for position detection or safety interlock applications.

Designed for vertical mounting, the through-hole package ensures stable mechanical retention and easy integration onto PCBs. The switch is rated for DC16V at 1A, making it suitable for low-voltage DC circuits commonly found in consumer electronics, security systems, and automation equipment. Its tactile response is calibrated with an operation force of approximately 30gf (grams-force), delivering a light yet distinct actuation feel that reduces user fatigue while offering positive detection feedback.

The housing is molded from high-grade Liquid Crystal Polymer (LCP) material, which provides exceptional dimensional stability, high heat resistance, and low moisture absorption. This insulation housing ensures robust electrical isolation and reliable performance across varying environmental conditions. Common applications include door/lid detection in portable devices, end-stop sensing in mechanical assemblies, and mode-selection circuits where a default-closed signal path is required until physical displacement occurs. This compact, durable switch combines sensitive actuation with long-lasting electrical integrity.
