Abstract

PURPOSE:To prevent to cut off the main power supply caselessly while loads are operated by providing a switch to turn ON and OFF the feeding of power supply and a load operation confirming device to detect and display the current flowing through a power supply line to the loads. CONSTITUTION:Power supply lines 101 are connected to or cut off from power supply lines 102 which are connected to the side of loads 4 through a switch 1. An ampere meter 3 is furnished to a current detection and display device 2, and the current is detected and displayed when a current flows to the power supply lines 102. Consequently, when the main power supply is required to cut off after the work is over and the like, it is decided easily by the current display of the ampere meter 3 whether the loads are in the operational condition or not. Therefore, the current detection and display device 2 functions as the load operation confirming means, and a case of cutting the switch carelessly can be prevented.
