GRI DS-01T-W Short Roller Ball Plunger Switch, Terminal Block, Closed Loop, with 360 of Ball Access and Screw Down Flange, White

Engineered for fast, reliable installation in security and access control systems, the George Risk Industries DS-01T-W Short Roller Ball Plunger Switch combines durable design with installer-friendly features. The DS-01 series uses a magnetic reed actuated by a rolling ball, giving 360-degree ball access that reduces wear and provides smooth travel for longer life—ideal for alarm, monitoring, and surveillance sensors. Its short, compact body eliminates the need for deep mounting holes, saving labor on retrofits and new installs, while the screw-down flange ensures secure retention in both horizontal and vertical orientations. The DS-01T-W comes as a closed-loop N.O. contact (Form A) and offers a terminal block option for clean, reliable connections into alarm panels and access control systems. UL/ULC approvals and a lifetime warranty mean you get code-compliant performance and peace of mind on critical perimeter and door applications. For technicians specifying plunger and toggle switches into security or surveillance projects, the DS-01T-W delivers dependable actuation, simplified wiring, and installation flexibility. Specify it for door jambs, frame mounts, or sensor arrays and streamline your next installation.
