ABSTRACT:
An electromagnetic relay to be used in applications such as DC motor reversing. The relay consists of two electromagnetic devices in a single enclosure with contacts configured in a so-called "H-bridge" circuit. Each of the devices has a movable contact element, while both devices have a common pair of normally closed and normally open stationary contact elements. Both electromagnetic devices have coil bobbins which are preferably identical in shape and are locked together by means of the common stationary contact elements without a need of additional fastening means. In this manner, the number of parts is minimized and the amount of adjustment required is reduced.
