Abstract
A solenoid-actuated latchable relay is controlled by a microprocessor that turns on at least one triac to selectively energize a solenoid coil with a desired polarity energization signal. The triac is only operated momentarily so that a single energization pulse is applied to the coil to move an associated magnetic plunger to a position corresponding to the polarity of the pulse. The magnetic plunger is latched in this position until another pulse is applied to change the position.
