Bolt switch contacts are suitable for monitoring door locking. The bolt switch contact has to be fitted into the frame striking plate in such a way that it is activated by the deadbolt. The signal can be evaluated or displayed in equipment such as alarm systems, building monitoring systems, visual and acoustic signal generators, etc.

Due to the rotary-mounted switch lever there are no dead bolt penetration restrictions. The slim design and the mounting screw provided enable assembly through the dead bolt cutout even in existing steel frames without striking plate. This can also be done afterwards, in mounted frames.
