ABSTRACT:
A housing for a small size electronic switching relay comprises an integral single part housing skeletal structure of insulating material which has an interior space which is divided by first and second partition walls which extend perpendicularly to each other into an armature chamber and first and second spring contact chambers. The housing includes a first and second set of spring contact holder slots defined therein which extend from the exterior of the housing into the respective first and second spring contact chambers. The first partition wall separates the armature chamber from the spring contact chambers and it has an actuator guide slot defined therein which extends from the armature chamber into respective ones of the first and second spring contact chambers. The housing has a wall bounding an end of the armature chamber with an armature biasing spring retainer slot. An armature coil is positioned in the armature chamber and an angle-shaped armature has one end which is attracted by the armature yoke within the coil and an opposite end which engages against an actuating member which extends through the first partition wall and to respective ones of the first and second spring contact chambers and moves one of the spring contacts toward or away from respective other ones of spring contacts which are held in the slots defined at the respective ends of the two spring contact chambers.
