A relay adapted to be mounted on a printed circuit board, and a method for mounting such relays. The relay includes the usual terminals (23, 24, 26 27, 28, 29) extending therefrom and adapted to be mounted on a printed circuit board (30) and electrically coupled to conducting paths on the board. In addition, however, the relay is provided with additional load terminals (56, 59, 62, 82, 92) which function as external connection junctions to connect the relay directly to the load being controlled via a circuit that completely bypasses the printed circuit board. According to a preferred embodiment, the relay includes stationary contact members formed to have not only board-mounted terminal portions extending therefrom but also external terminal portions for direct attachment to the load. By retaining the original load terminals on the relay and mounting them to the printed circuit board, added support is provided to help prevent dislocation of the relay from the board when the relay is connected to or disconnected from the load. These board-mounted load terminals can also be used for logic-sensing purposes or the like. Preferably, at least the stationary contact members are formed with an additonal pin portion (63, 64) also adapted to be attached to the board for additional support. The invention permits the use of less costly board material, more efficient utilization of board space, and, in general, a more reliably operating switching circuit. |
