摘要： In a case where a left-hand push-button switch is ON, a second relay RL2 is electrically de-energized to open a normally close contact RL2-1 of the second relay RL2 so 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 R3-1 of the right-hand push-button switch is opened. Thus, a third relay RL3 is 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.

摘要翻译： 在左侧按钮开关为ON的情况下，第二继电器RL2被断电以打开第二继电器RL2的常闭触点RL2-1，使得继电器触点电路RC断开。 如果在这种状态下右手按钮开关被切换到第二OFF状态，则右侧按钮开关的常闭触点R3-1被打开。 因此，第三继电器RL3不是断电，并且第一和第二电路都被截止，直到右手和右手按钮开关都返回到第一关闭状态。

摘要： When a left-hand pushbutton switch is on, a second relay (RL2) is demagnetized to open the normally closed contact (RL2-1) of the second relay (RL2) and a relay contact circuit (RC). When the left-hand pushbutton switch turns to a second off-state from the preceding state, the normally closed contact (R3-1) of the left-hand pushbutton switch opens, and a third relay (RL3) is not demagnetized until the right-hand and left-hand pushbutton switches is reset to a first-off state, so that power supply to the first and second circuits is interrupted.
