    • A battery powered, hand-held, lightweight electrical shocking device provides a visible and audible display of sparks continuously upon the operation of a switch. The device is capable of delivering a jolting shock. The display of sparks makes clear the nature of the device and serves as a deterrent to unruly persons. The device is comprised of a non-conductive housing in a generally annular shape, permitting it to be gripped in one hand. On one surface away from the hand are first and second conductive plates separated from each other by an insulator. The electrical circuit comprises a free-running multi-vibrator, a small transformer, a rectifier, a voltage doubler and an internal spark gap. The circuit can deliver a series of short duration, high voltage, low current electrical shocks from two penlight batteries.
    • 电池供电的手持式重量轻的电击装置在开关操作时连续地提供可见和可听见的火花显示。 该装置能够发出震动震荡。 火花的展示清楚了设备的性质,并且对不守规矩的人员起到了威慑作用。 该装置由大致环形的非导电壳体组成,允许一只手夹紧。 在离开手的一个表面上是通过绝缘体彼此分开的第一和第二导电板。 该电路包括自由运行的多重振动器,小型变压器,整流器,倍压器和内部火花隙。 该电路可以提供一系列短时间,高压,低电流的电击从两个笔记型电池。
