Abstract

PURPOSE:To simplify the constitution of circuits and improve the reliability of operation by connecting an operation switch circuit to the power source circuit of a microcomputer through a time constant circuit and a voltage detecting circuit. CONSTITUTION:When a switching element Q is turned on by turning on an operation switch 1, power is conducted to a voltage detecting circuit 9 through the operation switch circuit in the on condition and a time constant circuit (R4, C1) and when the voltage of the circuit 9 reaches a specified value or higher power is conducted from the voltage detecting circuit to the power source circuit of a microcomputer 6 and the computer is operated to hold the switching element in the on condition. For instanteneous power failure the input voltage of the circuit 9 is kept at the controlled voltage or higher by the time constant circuit (R4, C1) and the computer holds the condition before the power failure. On the other hand, when the power failure continues for more than the time determined by the time constant of the time constant circuit, the inlet voltage of the voltage detecting circuit drops to the controlled voltage or lower to reset the computer and the switching element is turned off by the operation signal of the computer.
