Patent ID: 8314698

Claim:
An anti-tamper assembly configured to sense the attempted removal of a body attached to a surface by a fastener, said anti-tamper assembly comprising: an anti-tamper access-blocking element positioned in an anti-tamper position proximal to said fastener; and an anti-tamper switch operably coupled with said access-blocking element, said access-blocking element causing the anti-tamper switch to assume a first switch condition when the access-blocking element is in said anti-tamper position, said anti-tamper switch configured to assume a second switch condition when said access-blocking element is moved from said anti-tamper position to a tamper position permitting access to said fastener for removal thereof, said anti-tamper switch being a mechanically actuatable switch including an actuating arm in engagement with said access-blocking element when the latter is in said anti-tamper position thereof such that the mechanically actuatable switch assumes said first switch condition, said actuating arm of said mechanically actuated switch moving in response to shifting of the access-blocking element to the tamper position thereof to cause the mechanically actuatable switch to assume said second switch condition, said fastener comprising a screw extending through said body and into said surface, said access-blocking element being mechanically coupled with said mechanically actuatable switch and comprising an elongated body in general axial alignment with said screw.
