Abstract

PURPOSE:To enable to operate a DC motor even after an overtravel detecting switch is operated by connecting the contact of an overtravel stop detecting switch and a diode in parallel with each other. CONSTITUTION:When a positive voltage is applied through normally closed contacts 3b, 4b of limit switches 3, 4 to a DC motor 1, a driving mechaism 2 moves in a direction of an arrow A. When the limit switch 3 is depressed to cause the normally closed contact 3b of the switch 3 to be opened, positive forward current is interrupted by a diode 5. Thus, the motor 1 is stopped. When a negative voltage is applied in this state, a DC current flows through the normally closed contact 4b of the switch 4 and the diode 5. Accordingly, the motor 1 is rotated reversely, and the mechanism 2 is moved in a direction of an arrow B. In this manner, the contact 3b of the switch 3 is closed.
