Abstract

PURPOSE:To prevent a switching controller from error operation by connecting a simultaneous depression preventing means for a switch to a remote control transmitting part in the switching controller. CONSTITUTION:When a self-restoration type pushbutton switch P1 is depressed, the status signal is detected by an operation detecting circuit 11-1 and a pulse signal from the circuit 11-1 is applied to a logical circuit 12-1. Since outputs of NOT circuits 14-2-14-n are logical ''1'' when other pushbutton switches P2-Pn are not depressed, the status signal of the pushbutton switch P1 is supplied to an operational pulse generating circuit 13-1 through the logical circuit 12-1 and a pulse signal generated in the circuit 13-1 is converted into a transmitting code by an encoder circuit 4. If an operator depresses by mistake other pushbutton switches P2-Pn under the condition where the swtich P1 is ON, logical circuits 12-2-12-n are closed because a NOT circuit 12-2 has been already turned to ''0'', so that the status signals of the switches P2-Pn are not transmitted to the encoder 4.
