| A tamper detection switch is 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, low-cost magnetic switch assembly (16, 16a) is provided having an easily fabricated housing (24, 24a) and cover (29, 29a) formed of non-conducting synthetic resin material. A pair of electrically conductive switch elements (30, 32, 30a, 32a) are positioned in spaced relationship with the housing (24, 24a) along with a body (40, 40a) shiftable between a first position in simultaneous contact with the switch elements (30, 32, 30a, 32a), and a second position out of such simultaneous contact. The housing (24, 24a) is also equipped with a first attractive component (38, 38a) which magnetically reacts with the body (40, 40a) to hold the latter in one of the positions thereof when the assembly (16, 16a) experiences a first magnetic field condition, but allows the body (40, 40a) to move to the other of the positions thereof when a second magnetic field condition is experienced adjacent the assembly (16, 16a). | ||||||

| A magnetic switch (10) for detecting relative movement between first and second members (12, 14) is provided which includes a switch assembly (20, 50, 70) for mounting in one of the members (12, 14), an attractive component (22, 54, 76) for mounting on the other member; the assembly (20, 50, 70) preferably includes plural switch elements (40, 26, 70, 56, 92, 80) and a conductive, shiftable body (44), whereas the component (22, 54, 76) is magnetically attractive to the body (44). The first switch elements (40, 70, 92) are preferably formed of a magnetically attractive material while the body (44) is fabricated from permanently magnetized material, so that the body (44) remains permanently magnetically coupled with the element(s) (40, 70, 92) in all positions of the body (44). Alternately, the switch assemblies (20, 50, 70) can be used as proximity detectors so as to generate a signal in the presence of an adjacent ferrometallic or permanently magnetized object (108). | ||||||

| 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). | ||||||

| 49 | Pull-apart safety switch with magnetic means for machines | US3801767D | 1972-12-11 | US3801767A | 1974-04-02 | MARKS R |
| Several embodiments of pull-apart safety switches are disclosed that are for use in connection with machines from which the operator may be thrown or which he may leave with the machine remaining in motion. Each switch includes a mount to be secured to the machine and a cover so attached to the mount that it may be pulled therefrom. The mount has leads to be included in the machine circuit that is to be controlled. The cover is provided with a flexible member attachable to the operator and of sufficient length to enable him to make normal movements without pulling the cover from the mount. Each switch also has a conductor and means releasably holding it in a first relationship with the contacts when the cover is attached and a second relationship therewith when the cover is pulled free. In one of the two relationships, the control system is operative to maintain the machine in operation. Except when the control circuit is an ignition system having a magneto, said one relationship is the first relationship and in that case, said one relationship is the second relationship. In most embodiments, the cover is magnetically held in place and in second relationship circuit control, the conductor is within the mount and is held from moving into its circuit-closing position until the cover is pulled free, the conductor then being operatively positioned magnetically, resiliently, or by both such means.
