Television device confirming backward of vehicle

Abstract

Abstract PURPOSE:To simplify all the systems used for a 12V vehicle, by providing a resistor and a changeover switch for a monitor television section. CONSTITUTION:With a main switch 5 to be closed, when a manual switch 11 is closed or a back gear switch 8 is closed, DC 24V of a battery 4 is reduced to a half with a resistor 21 and about 12V is applied to the coil of a monitor relay 20. In case of a 12V vehicle, a changeover switch 22 is selected to the terminal B, an up converter 18 is provided between a main fuse 6 and the manual switch 11 of a monitor television 1', allowing to set system constitution not requiring a 12V relay.
