ABSTRACT:
A relay test assembly including a majority of parts adapted to be injection molded and capable of withstanding large and rapid swings in temperature and humidity. These include a central approximately cylindrical body portion having a plurality of channels of generally-conical shape running therethrough generally-parallel to the axis of the body portion. The channels provide easy entry and straightening to leads of a relay Each channel includes a spring which may be brought to bear against a lead positioned in the channel to provide positive electrical contact to the lead while requiring no force to insert the lead. A sleeve positioned about the body portion is shaped to force the springs into contact with the relay leads.
