Anti-tamper assembly for surface mounted security switch

An anti-tamper assembly operable to sense the attempted removal of a body attached to a surface by a fastener, said anti-tamper assembly comprising:

• an anti-tamper magnetic component positioned in an anti-temper position proximal to said fastener;
• and
• a magnetically actuatable anti-tamper switch operably coupled with said anti-tamper magnet, said anti-tamper magnetic component causing the anti-tamper switch to assume a first switch condition when the anti-tamper magnetic component is in said anti-tamper position, said anti-tamper switch operable to assume a second switch condition when said anti-tamper magnetic component is moved from said anti-tamper position to a tamper position permitting access to said fastener for removal thereof.

An anti-tamper alarm assembly operable to detect relative movement between first and second members each presenting surfaces, comprising:

• an alarm section secured to the surface of said first member by a fastener extending through the first member surface, said alarm section including a sensor operable to detect said relative movement between said first and second members, an anti-tamper magnetic component in an anti-tamper position proximal to said fastener, and a magnetically actuatable anti-tamper switch operably coupled with said anti-tamper magnet, said anti-tamper magnetic component causing the anti-tamper switch to assume a first switch condition when the anti-tamper magnetic component is in said anti-tamper position, said anti-tamper switch operable to assume a second switch condition when said anti-tamper magnetic component is moved from said anti-tamper position to a tamper position permitting access to said fastener for removal thereof;
• and
• an alarm circuit coupled with said anti-tamper switch and operable to generate an alarm signal in response to said movement of said anti-tamper magnetic component to said tamper position.
