Abstract

PURPOSE:To reduce the number of operation lines, by providing an operation switch between the power supply and the load, and illuminating or distinguishing the display light in the push button switch corresponding to the state of load and no- load with a voltage of high and low two types, when the switch is operated with the operating push button switch. CONSTITUTION:An operating switch 3b consisting of a main contact M, auxiliary contact A, resistor R, operating coil C and two diodes is connected between the power supply 2 and the load 1, and the control power supply 4b consisting of a transformer in parallel with the load 1 producing high and low two secondary voltages V0 and V1 is connected to the power supply 2. With this constitution, the control power supply 4b is operated by using the push button B being the self- restored type operating switch and the operating push button switch 5b incorporating the load state display light, and a high voltage V0 is fed to the display lamp by using the connection line when the switch 3b is closed and a low voltage V1 is fed when open for illumination or distinguishment. Thus, the operating lines from the switch 5b can be two.
