  • Capacitor discharge circuit
    Patent number: 4504773
    Abstract: A capacitor discharge circuit constructed by a combination of a mechanical switch and an electronic switch. The electronic switch is automatically turned on with a predetermined time delay after closing of the mechanical switch. The mechanical switch is used to completely separate a high voltage-large capacity capacitor from a load when the discharge operation is not required. The wear and tear of contacts in the mechanical switch can be avoided by the delayed operation of the electronic switch.
