Abstract

PURPOSE:To make a circuit form small-size and make high frequency switching possible by grounding one main electrode of a switching element and connecting the other main electrode to a positive or negative power source through impedance in a TV receiver. CONSTITUTION:NPN-type transistor Tr8, PNP-type Tr9 and NPN-type Tr2 are used as the first switching element, the second switching element and the third switching element respectively. Collectors of Tr2 and S are connected to the positive pole side of power source 4a through load 3, and the collector of Tr9 is grounded through capacitor 13, and the base common connection point of Tr8 and 9 is connected to the positive pole side of power source 4b through a series circuit of capacitor 14 and coil 15. The connection point between capacitor 14 and coil 15 is connected to the collector of NPN-type Tr16, and the emitter is grounded; and when the switching pulse changed to a ground level and a positive level is inputted, terminal 1 and the base of Tr16 are connected.
