Abstract

PURPOSE: To reduce power consumption by monitoring the presence or absence of the voltage output on the load side of a contact, and energizing individual coils based on the logical product of the existence state signal and the state signal of an operating switch.
CONSTITUTION: When an operating switch 16 is not turned on while the contact 11 of a latching relay 4 is kept open, no exciting current flows in a set coil 7a and a reset coil 7b, and the contact 11 is kept open. When the switch 16 is turned on, an output signal x=H is outputted from an AND gate 18a, and an exciting current flows in the coil 7a to close the contact 11. When the contact 11 is closed, the excitation of the coil 7a is stopped, but the closed state of the contact 11 is maintained. When the contact 11 is opened under this condition, a transistor Tr 15a is closed to close the contact 11. When the switch 16 is turned off, 'H' is outputted from an AND gate 18b, and an exciting current flows in the coil 7b to open the contact 11. When the contact 11 is closed under this condition, a transistor Tr 15b is closed to open the contact 11.
