Abstract
PURPOSE: To hold a plunger at a driving position even though a switch is stopped during the switching action, by keeping the direction of a current flow unider the state before the switching action by an FF circuit.
CONSTITUTION: In the case a switch 11 is connected to a contact C1, a current from a base-voltage power supply 10 enables an FF circuit 12 to send an output voltage from a power terminal a1 but not to send an output power from a power terminal a2. Therefore, a transistor T1 is turned on, TrT2 is turned off, pnp-type TrT3 is turned on, pnp-type TrT5 is turned off, npn-type TrT4 is turned on, pnp-type TrT6 is turned off, and a current flows in an electromagnetic coil 1 in the arow direction. During the period the switch 11 is turned from contacts C1WC2, the circuit 12 holds the previous state and sends the output voltage. Therefore, a plunger is held at the drived position by the current flowing in the coil 1 unit the switch 11 is connected to the contact C2. When the switch 11 is connected to the contact C2, the state of the circuit 12 is changed, and the current flows in the coil in the direction opposite to the arrow.
