Abstract: Integral posts on the molded base limit rotation of a lower contact carrier, and a contact guide limits rotation of an upper contact carrier, the carriers being spring biased for slidable movement on a lifter post attached to the armature of the relay.

Abstract: A stop member is hingedly mounted to a base member which clips onto a vehicle license plate of the type which is pivotably mounted to a vehicle and functions as an external cover which hides the usual fuel tank cap and fill port. After the license plate has been swung into an open position the stop member can be pivoted from an inoperative position, wherein it lies parallel to the rear face of the license plate, to an operative position wherein it lies in a plane perpendicular to that of the license plate and abuts the rear wall of the vehicle to hold the plate in a open position.
