Honeywell Interlock Door Close Limit Micro Switch

Compact Honeywell SPDT microswitch rated 10 A at 125/250/277 V AC with bullet‑nose plunger; ideal for door‑close sensing in elevator Honeywell locks.

This Honeywell button switch is a precision snap‑action microswitch designed for panel‑mount installation and momentary action applications such as door‑close sensing in interlock systems.
Its single‑pole double‑throw (SPDT) configuration supports one‑common, one‑normally‑closed and one‑normally‑open contact set, making it an excellent fit for detecting the closed position of access doors or interlock panels in lift and safety systems.
Its bullet‑nose plunger actuator provides reliable repeatable actuation, and the compact housing with quick‑connect/solder terminals enables rapid installation. Rated for up to 10 A at 125/250/277 V AC, it supports a broad range of control circuits.
The device operates within a wide temperature range and is built to mechanical endurance standards for consistent performance in demanding environments.
