3/4" Magnetic Contact Switch 24" Lead, Form A Normally Open AMS-25A-I

The AMS-25A-I is a UL-listed magnetic contact switch designed for reliable door and window monitoring in commercial security applications.

The normally-open Form A contact closes when the magnet approaches, triggering alarms or access-control systems.

Installation is straightforward with press-fit mounting and self-locking features that work in both DIY and professional settings. The 24" lead with 22 AWG wire provides flexible placement options, and the white finish blends discreetly into most environments. Powered by DC voltage, this contact requires no batteries and integrates easily into existing wired security networks.

Ideal for commercial buildings, retail storefronts, warehouses, and any facility needing cost-effective perimeter monitoring on steel door installations. The 1-year limited warranty backs the product's durability in demanding security roles.
