Lift Brake Switch – Roller Plunger Microswitch SPDT 15A with Screw Terminals

Heavy-duty SPDT roller wheel brake switch for elevators and lifts; rated 15A, with screw terminals and long mechanical life.

This high-performance microswitch is commonly used as a brake switch in lift and elevator systems. It features a roller plunger actuator for precise mechanical triggering and a single-pole, double-throw (SPDT) contact configuration. Built with durable materials and a long mechanical cycle life, this switch is suitable for demanding control applications. The body includes panel mounting holes and screw-style terminals for secure electrical connection. Ideal as a replacement in existing systems that require a mechanical roller-style limit switch.
