    • Tamper-resistant switch assemblies (26, 162) are provided including a first movement-sensing switch (28) and a second tamper-sensing switch assembly (30), the latter including a switchable component (32) and an actuating component (34). Preferably, the switch (28) and switch assembly (30) are housed within an encapsulated switch module (70, 114, 164), with the actuating component (34, 118, 138, 166) positioned above or to the side of the module (70, 114, 164). Mounting structure (36) serves to support the module (70, 114, 164) within a mounting opening (90, 112, 148) and is operable to prevent removal of the switchable component (32) and actuating component (34, 118, 138, 166) without significant relative shifting movement between the switchable component (32) and actuating component (34, 118, 138, 166). Any attempted tampering results in such relative shifting movement, thereby triggering an alarm. In another aspect, the invention provides switch apparatus (182) including a magnetic ball switch (32) with a first biasing magnetic component (194) and a second operating magnet component (196). Adjustment structure (190, 192) permits selective adjustment of the position of magnetic component (194) in order to permit tuning of the apparatus (182) so as to prevent defeat thereof by means of a defeat magnet (198) positioned between the magnet components (194, 196).
    • 提供了防篡改开关组件(26,162),包括第一移动感测开关(28)和第二篡改感测开关组件(30),后者包括可切换部件(32)和致动部件(34) 。 优选地,开关(28)和开关组件(30)被容纳在封装的开关模块(70,114,164)内,致动部件(34,118,138,166)位于模块的上方或侧面 (70,114,164)。 安装结构(36)用于在安装开口(90,112,148)内支撑模块(70,114,164),并且可操作以防止可切换部件(32)和致动部件(34,118,138)的移除 ,166),而在可切换部件(32)和致动部件(34,118,138,166)之间没有显着的相对移动运动。 任何尝试的篡改导致这种相对移动运动,从而触发报警。 另一方面,本发明提供了包括具有第一偏置磁性部件(194)和第二操作磁体部件(196)的磁性球开关(32)的开关装置(182)。 调节结构(190,192)允许选择性地调整磁性部件(194)的位置,以便允许调节装置(182),以防止位于磁体部件(182)之间的失败磁体(198)的失效 (194,196)。

    • A secure magnetic sensor has a first magnetic switch activatable by a first magnetic field and a second magnetic switch activatable by .a second magnetic field which is stronger than the first magnetic field. The first magnetic switch is electrically connected in series to the second magnetic switch. In the default position, the first magnetic switch is in the open position whereas the second magnetic switch is in the closed position. When the secure magnetic sensor is normally activated, the first magnetic switch is activated to close. However, when the secure magnetic sensor is tampered by the addition of a supplemental magnet, this causes the second magnetic switch to be in an open position thereby sounding an alarm.
    • 安全磁传感器具有可由第一磁场激活的第一磁性开关和可由比第一磁场强的第二磁场激活的第二磁性开关。 第一磁开关与第二磁开关串联电连接。 在默认位置,第一磁性开关处于打开位置,而第二磁性开关处于关闭位置。 当安全磁传感器正常启动时,第一个磁性开关被激活以关闭。 然而,当通过添加补充磁体来篡改安全磁传感器时,这使得第二磁性开关处于打开位置,从而发出警报。
