PURPOSE:To make it possible to pick up a key after turning on a main electric circuit by holding the main electric circuit in an on-state with a holding circuit and separately providing an operating means for turning off the main electric circuit. CONSTITUTION:A key 1 is inserted into a key hole and then turned at a specified angle, to thus turn the main switch of an electric system. There is provided a holding circuit for holding the on-state when the main switch of the electric system is turned on. Thus, the on-state is held and thereafter the key 1 is pulled out. There is provided a switch 4 for making the holding circuit or the electric system off. In order to connect the key 1 to the operator's body, there is provided a device comprising a band 6 with a lock, a winder 7 and a string for connecting the winder 7 to the key 1. Since it is not required for the key 1 to be left inserted into the key hole, it is possible to prevent the burglar accident of a car. |
