Door Switch 3A NC 5mm Black Handle – 1 Pcs

Description

This door switch is engineered for safety-and-control applications: in its normally closed (NC) configuration, the circuit remains connected when the door is in the rest position (i.e., closed), and when the door is opened (or the actuator is moved) the contact opens – thereby interrupting the circuit. This fail-safe behaviour ensures that if the door is forced or opened unexpectedly, the system detects the change via the contact break.

The switch features a black handle or actuator, offering clear visual contrast and durability, and incorporates a precise 5 mm travel/actuation dimension (or a 5 mm handle diameter as required) for reliable mechanical engagement. It is typically built with rugged mounting hardware, secure screw-clamp or terminal connections, and is rated for use in industrial or cabinet environments (often 250 V AC/1-10 A or similar), with mounting diameters and bezel materials chosen for durability and standard panel-cut-outs. These characteristics make it suitable for monitoring guard-doors, machine-enclosures, wardrobe/cabinet doors, or access-control points where the door-closed state must be continuously monitored until an open event triggers an action.
