Abstract: A method of assembling a relay device adapted to be removably mounted in plug-on relation to male terminals. The relay device has a housing portion with a pair of cavities therein adapted to seat a pair of female terminals electrically connected to electrical leads in circuit means of the relay device. In this method, the female terminal pair are arranged with respect to the cavity pair so that the female terminal pair may be seated therein. A cover is releasably secured onto the housing portion in a predetermined assembled position to capture the female terminal pair in the cavity pair, and a pair of openings in the cover are disposed with respect to the cavity pair and the female terminal pair for accommodating the passage through the opening pair of the male terminal into electrical contacting engagement with the female terminal pair when the relay device is removably mounted in the plug-on relation with the male terminals.

Abstract: A relay device adapted to be removably mounted in plug-on circuit relation with at least a pair of male terminals of an electrically energized apparatus. The relay device has receptacle means including a first portion with a pair of cavities for respectively receiving in predetermined seated position therein a pair of female terminals adapted for electrical contacting engagement with the male terminal pair. A cover portion is disposed in a predetermined assembled position on the first portion so as to generally enclose the chambers. The cover portion includes means for positioning engagement with the female terminal pair so as to maintain them generally against displacement from their predetermined seated positions in the cavities and a pair of openings communicating with the cavities and generally aligned with the female terminal pair for passing the male terminal pair into the cavities so as to be received in the electrical contacting engagement with the female terminal pairs.
