    • An apparatus and method is disclosed for providing an impact switch that is non-critical to temperature variations and preload pressures. The impact switch consists of a plate having a pair of parallel slots disposed therethrough defining a beam capable of flexing. A mass is located on one side of the beam and a piezoelectric crystal is located on the contact side of the beam. The plate is covered by a housing having a pin extending therethrough. The cover is placed such that when the required force is exerted on the beam it will flex causing the piezoelectric crystal and pin to come in contact thereby providing a voltage that will trigger the associated circuitry. The force required to make contact can be varied by changing the weight of the mass and/or the material or dimension of the beam.
    • 公开了一种用于提供对温度变化和预加载压力非关键的冲击开关的装置和方法。 冲击开关由具有一对平行狭槽的板构成,该平行狭槽设置成穿过其限定能够弯曲的梁。 质量块位于梁的一侧,压电晶体位于梁的接触侧。 板被具有延伸穿过其的销的壳体覆盖。 盖被放置成使得当所需的力施加在梁上时,其将弯曲,导致压电晶体和引脚接触,从而提供将触发相关电路的电压。 接触所需的力可以通过改变质量的重量和/或梁的材料或尺寸来改变。

    • An apparatus is disclosed providing a hermetically sealed impact switch that is non-critical to humidity and less susceptible to corrosion. The impact switch consists of a cover, a base, and a flexible beam disposed there between. Mounted in the cover and extending into a cavity created by the cover and flexible beam is a pair of contact pins, each electrically isolated from the cover and each other. Mounted to the flexible beam is a mass, which may be a piezoelectric crystal or the like. By utilizing a pair of pins, rather than one pin, the flexible beam may be mounted directly to the cover and base without an insulating bonding material which can cause corrosion of the contact pins.
    • 公开了一种提供密封冲击开关的装置,其对湿度非常重要并且不易腐蚀。 冲击开关由一个盖子,一个基座和一个设置在其间的柔性梁组成。 安装在盖中并延伸到由盖和柔性梁产生的空腔中的是一对接触销,每个接触销与盖彼此电隔离。 安装到柔性梁的是质量块,其可以是压电晶体等。 通过利用一对销而不是一个销,柔性梁可以直接安装到盖和基座上而没有绝缘接合材料,这可能导致接触销的腐蚀。
