Abstract: A switch is described that includes a plunger (20, FIG. 1 ) moveable between up and down position and having upper contacts (22, 24) and lower contacts (26, 28). When the plunger is moved to a down position, opposite ends of the upper contact (22) move down against first and second terminals (12, 14) to interconnect them. When the plunger is moved to an up position, opposite ends of the lower contact (26) move up against the first terminal (12) and a third terminal (16) to interconnect them. The plunger can move within a hole in a circuit board and carry two upper and two lower contacts to connect four terminals in two different ways. Each terminal can include upper and lower terminal pads (120, 122, FIG. 5 ) lying respectively on upper and lower surfaces of the circuit board and interconnected through plated-through holes (124) in the board.
