Bolt switch contacts
Bolt switch contacts are suitable for monitoring the door locking. To do so, a bolt switch contact is fitted into the frame striking plate in such a way that it is activated by the lock bolt. The signal can be evaluated or displayed in equipment such as alarm systems, building monitoring systems, control panels, and visual and acoustic alarm devices.
