A bobbin assembly is disclosed that includes a first bobbin and a second bobbin. The second bobbin is configured substantially similar to the first bobbin. The first and second bobbins include a first flange and a second flange disposed at opposite ends of a central core. The first flanges include terminal receiving cavities and wire posts for terminate a wire wound around the central core. The bobbin assembly may be formed by mating either the first flanges or the second flanges together.

Bobbin assembly

An electromagnetic relay has a relay coil, an armature, a pusher and a contact system. The armature is actuated by the relay coil, and linked to the pusher to drive the pusher to operate the contact system. A set of stationary contact springs and a set of moveable contact springs have a gap separating them. The moveable contact springs connect to the pusher and to a pivot point. The stationary springs have a notch therein adjacent to the base structure portion. The pusher movement causes the stationary contact springs and the moveable contact springs to engage or disengage, and to automatically adjust the overtravel angle of the stationary contact springs relative to the moveable contact springs by bending the stationary contact spring at the notch of the stationary contact spring.

Relay with automated overtravel adjustment

An electromagnetic relay has an overtravel adjustment to set the gap in the contact arrangement. The armature is actuated by a relay coil and linked to a pusher to drive the pusher to operate the contact system. The pusher includes a rotary dial disposed in a slot on the pusher adjacent to the armature. The rotary adjustment increases or decreases a gap of the contacts to provide an over-travel adjustment. The pusher includes bifurcated tines defining the slot for receiving an armature linkage and the rotary adjustment. The rotary adjustment includes a head and a post depending from the head. The post is disposed within the slot and the head portion in contact with the armature linkage portion. The rotary adjustment sets the distance between the forward edge and the armature to achieve the desired overtravel for the contact arrangement.
