| 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. | ||||||
