Abstract:
A relay apparatus comprising:at least one self-maintaining relay and another self-maintaining relay which are provided corresponding to input terminals; a dielectric which charges and discharges electrical energy; energizing means which energizes said dielectric and charges said electrical energy to said dielectric; one starting means which outputs a start signal to an input side of the one self-maintaining relay and enables a self-maintaining circuit of the one self-maintaining relay to be formed; another starting means which is operated by a self-maintaining operation of the one self-maintaining relay, outputs the electrical energy charged to said dielectric as a start signal, and enables a self-maintaining circuit of the other self-maintaining relay to be formed; and output means which is operated by the self-maintaining operations of the one self-maintaining relay and the other self-maintaining relay and outputs an output signal to an output terminal connected to a load, and wherein the one self-maintaining relay and the other self-maintaining relay comprise an electromagnetic relay and the other starting means comprises an electronic circuit including said dielectric.
