PROBLEM TO BE SOLVED: To provide a relay having a high current capacity by avoiding a spot corrosion by local heating or accumulation of an oxide. SOLUTION: In this electric relay using a conductive liquid in a switching mechanism, a pair of movable switching contacts are arranged between a pair of fixed contact pads. The surface of each contact supports a conductive droplet of a liquid metal or the like. An actuator is operated to move the pair of switching contacts, and the gap between one of the fixed contact pads and one of the switching contact is closed, whereby the conductive droplet is adhered to make an electric circuit. At the same time, the gap between the other fixed contact pad and the other switching contact is increased, and the conductive droplet is separated to interrupt the electric circuit.
