Abstract
Two sets of two relay switches, which charge a pump capacitor and a reservoir capacitor of a charge pump type voltage converter, are formed respectively by a set of plural piezo-electric relays, and both the capacitors are formed together with the piezo-electric relays on one substrate. Electrodes are provided respectively on both surfaced of a piezo-electric film, and operating sections are operated by applying a power-supply voltage thereto, and a movable terminal is brought into contact with a counter terminal plate due to deformation of the operating section so that the piezo-electric relays are turned on.
