Compact Security Limit Switch and Security Lock for electrical and mechanical securing of swing, lifting and sliding doors. When the actuator is pressed in, the contact is closed. The Security Lock, working on the zero-current principle, also locks the actuator at the same time when appropriately wired. This mechanically prevents the doors from being opened even in the event of a power failure or impermissible operating states. In the event of an emergency, the Security Lock can be opened without power using the supplied triangular socket wrench.Wiring diagram: Security Lock compact 2NCIllustration of circuits: Security Lock compact 2NC
