| A tamper detection switch is disclosed primarily for use in an enclosure of a security system component. The enclosure has a base and a cover that may be repositioned relative to the base. One of the cover and the base holds a conductive magnetic element free to translate within a predetermined range generally perpendicular to the respective cover or base. The other of the cover and the base holds at least two ferrous metal contacts of an open tamper circuit in proximity of a conductive magnetic element. In the closed position the conductive magnetic element bridges the ferrous contacts and closes the tamper circuit. Attempts to tamper with the enclosure separate the ferrous contacts from the conductive magnetic element, opening the tamper circuit and signaling a possible attack. | ||||||

| An improved magnetic switch (10) is provided which is designed for use in an alarm circuit (52) in order to detect relative movement between first and second members such as a door (14) and frame (12), so as to signal unauthorized opening of the door (14). The switch (10) includes a switch assembly for mounting in frame (12) and having first and second switch elements (40, 42), a permanently magnetized, shiftable body (44) adjacent the elements (40, 42), and a first attractive component (36). Additionally, the switch (10) has a second attractive component (22) for mounting to the door (14), which is in the form of a ferromagnetic component such as a permanent magnet (50) or steel plate (60). In use when door (14) is closed and circuit (52) is armed, the magnetic attraction between body (44) and component (22) shifts the body (44) to a switch-closed position in simultaneous contact with the switch elements (40, 42). If the door (14) is opened, the magnetic attraction between body (44) and component (36) moves the body to a switch-open position out of simultaneous contact with the switch elements (40, 42), thus triggering circuit (52). If an intruder attempts to defeat the switch (10) through an external magnet (58), this again moves the body (44) to a switch-open position, triggering the circuit (52). | ||||||

| 37 | High security switch assembly | US13019769 | 2011-02-02 | US08487726B2 | 2013-07-16 | Randall Woods; Joseph Hedeen |
| Tamper-resistant switch assemblies are provided including a first movement-sensing switch and a second tamper-sensing switch assembly, the latter including a switchable component and an actuating component. Preferably, the switch and switch assembly are housed within an encapsulated switch module, with the actuating component positioned above or to the side of the module. Mounting structure serves to support the module within a mounting opening and is operable to prevent removal of the switchable component and actuating component without significant relative shifting movement between the switchable component and actuating component. Any attempted tampering results in such relative shifting movement, thereby triggering an alarm. | ||||||
