ABSTRACT:
An electromagnetic solenoid relay assembly in which all the electrical connections are located on one end thereof. The solenoid relay assembly of the invention is attached to a printed circuit board by a spring clip member. The relay assembly of the invention includes a bobbin with an electromagnetic coil wound thereon, a stationary core located in the bore of the bobbin, and a movable core slidably located in the bore which is attracted to the stationary core when the electromagnetic coil is energized. An electrical contact is located on the opposing faces of the stationary and movable core members such that an electrical circuit through the two is completed when the coil is energized. A bias force on the movable core member is provided by a spring which urges the movable core away from the stationary core. A pressure plate member carrying a plurality of electrical contacts thereon makes electrical contact to the spring which, in turn, is electrically connected to the contact on the movable core member. The electrical connection to the contact on the stationary core member is made by a bus bar which is connected to the contact at one end and a contact on the insulative member at the other end.
