Flush-mounted Key Switch – Momentary Action (Square Face, Euro Cylinder)
This flush-mounted key switch is a compact, square-faced control device, operated via Euro-profile key cylinder, designed for momentary (non-latching) contact action. Ideal for applications where a brief key‑turn should activate or release a door control signal while the key is held.
Key Features & Benefits
Momentary Contact Action The switch only makes contact while the key is turned (i.e. “on” only during turning), reverting to its normal state when released.
Flush-mounted Installation Designed to be mounted into a standard flush box (e.g. single-gang) for a clean, professional finish.
Square Faceplate Design Square trim plate provides a tidy aesthetic, aligning with many modern door control accessories.
Euro-cylinder Operated Accepts standard Euro-profile half-cylinders (user-supplied or matched) for key access.
Compact & Discreet Low profile and minimal protrusion, suitable for tight spaces near doorways or control panels.
Versatile Wiring Suitable for integration in automatic door control systems, safety overrides, program selectors, or controlled access functions.
