Abstract
In a case where a left-hand push-button switch is ON, a second relay RLis electrically de-energized to open a normally close contact RL-of the second relay RLso that a relay contact circuit RC is opened. If, in this state, a right-hand push-button switch is shifted to a second OFF state, a normally close contact R-of the right-hand push-button switch is opened. Thus, a third relay RLis not electrically de-energized and a first and a second circuits are in cutoff until both the right-hand and the left-hand push-button switches are returned to a first OFF state.
