| Summary: | An electromagnetic relay includes a power reducing arrangement for automatically reducing the power consumption of the relay. The relay includes a pair of cooperable relay contacts (19, 25) and a switch member (27, 31) which is movable with the movable contact (19) relative to at least one coil terminal (13) for controlling the current level in the electromagnetic coil (7). In response to energisation of the electromagnetic coil (7), a movable contact plate (15) simultaneously moves the movable relay contact (19) into engagement with the other contact (25) and the switch member (27) with respect to the coil terminal (13) to cause either a part of the electromagnetic coil to be connected in series with another part of the electromagnetic coil or alternatively a resistor to be connected in series with the coil (7). As a result, a holding current level is produced which is less than the driving current level. … A microwave cooking oven, may be made more compact and cheaper with such a relay or relays in a control device therefor. …… |
