ABSTRACT OF THE DISCLOSURE A relay includes a internal power reducing mechanism for automatically reducing the power consumption of the relay without any extra power reducing circuit. The relay includes a pair of relay contacts for alternately opening and closing with respect to each other, an electromagnetic coil for generating a magnetic force, a switch member and at least one coil terminal for controlling the current level in the electromagnetic coil ,and a movable contact plate. To reduce the power consumption of the relay, in response to the magnetic force of the electromagnetic coil, the movable contact plate simultaneously moves one of the relay contacts with respect to the other and the switch member with respect to the coil terminal. By this movement of the movable contact plate, the pair of relay contacts are closed, and a part of the electromagnetic coil or a resistor connected in series with the electromagnetic coil is short-curcuited. As the result, a holding current level is limited less than a driving current level. A cooking apparatus ,such as,e.g. a microwave oven, can be made more compact and cheeper with this relay in a control device. - 17 -
