Abstract

PURPOSE: To prevent malfunction attended with inversion due to vibration of a latch relay or the like by reading information of setting state of the latch relay from a nonvolatile memory every application of power and setting the latch relay to the setting state. CONSTITUTION: A control means 3 reads information of a setting state of a latch relay 1 from a nonvolatile memory 2 every application of power to set the latch relay 1 in the setting state. The latch relay 1 closes its contact (a) when a control relay aL is operated and its contact (b) is opened and the state is maintained even when no power is supplied. When a control relay bL is activated, the contact (b) is closed and the contact (a) is opened and the state is maintained. A CPU reads the setting state of the latch relay 1 stored in the nonvolatile memory 2 to control the latch relay 1 depending on the state.
