Patent ID: 7944334

Claim:
A tamper-resistant switch assembly operable to detect relative movement between first and second members, one of said members having an apertured outer surface and a hollow interior space inboard of said outer surface and in communication with said aperture, said switch assembly comprising: a first movement-sensing switch located within said hollow interior space of said one member inboard of said outer surface and operable to switch between first and second separate movement-sensing states in response to relative movement between said first and second members; a second tamper-sensing switch assembly located within said hollow interior space of said one member inboard of said outer surface and including a switchable component and an actuating component, said switchable component and actuating component being relatively shiftable, said switchable component switchable between first and second tamper-sensing states in response to said relative shifting between the switchable and actuating components; and mounting structure operable to support said first switch and second switch assembly within said hollow interior space of said one member and inboard of said outer surface thereof in a normal operating position wherein said first switch will sense said relative movement between said first and second members, and to cause said relative shifting between the switchable component and the actuating component of said tamper switch assembly, in the event of attempted detachment of at least one of the components of said second switch assembly, the first switch, or both thereof, from said normal operating position, said switchable component of said second tamper switch assembly being a magnetically actuatable switch operable to switch between said first and second separate tamper-sensing states in response to a change in magnetic field conditions adjacent said switchable component, said actuating component of said second tamper switch assembly located proximal to said switchable component.
