Filed: 1985-10-17
Abstract: PURPOSE:To cause a controller to safely act without supplying electric power to a load for a long time even when a short-circuiting fault occurs at the contact of a touch type input section or a heavy substance, etc., continuously contacts with the input section as if a person operates the input section, by performing counting time comparison at a logical control section having the 1st and 2nd prescribed times and load control in accordance with the comparison information. CONSTITUTION:The signal of a touch type input section 2 is counted by a counting section 3 and, when the signal continues for more than the 1st prescribed time T1, it is discriminated that prescribed input signals are inputted and a logical control section 4 starts load control. If the counting section 3 further continuously counts the signal and the input signal exists even after the 2nd prescribed time T2 which is longer than the 1st prescribed time T1 has passed, it is discriminated as abnormal and the load control is stopped by the logical control section 4. Therefore, continuation of automatic load control due the fault of the input section 2 or some external main causes is eliminated.
