Abstract
To be utilized with a conventional structural alarm system having a plurality of alarm wires which carry a constant current flow, an alarm continuity switch which includes at least two identical contact assemblies, each of which have a contact housing. Included as part of the contact housing is a front main face wherein a generally narrow vertical channel with a first contact extending therefrom is disposed, and a generally wide mouth recess having a second contact therein is disposed. The first and second contacts are positioned such that they will slidingly engage with opposing contacts of a confronting contact assembly, the first contact of one assembly engaging the second contact of a second assembly, and vice versa. Further, the contact housing, which is secured to the structure, will include first and second wire terminals, each respectively secured to the first and second contacts and adapted to maintain the constant current flow through the alarm wires.
