  • Patent number: 6180905
    Abstract: A pushbutton switch (10) includes a printed circuit board (14) having first and second traces (18, 20) spaced circumferentially apart about an axis (22) and a housing (40) connected to the circuit board. The housing (40) includes a chamber (80) in which a movable assembly (100) is partially disposed. The movable assembly (100) has electrical contacts (198) for engaging one or the other of the first and second traces (18 and 20) on the circuit board (14). A button (12) is connected with the movable assembly (100). The button (12) is manually depressible toward the circuit board (14). A spring (220) biases the movable assembly (100) and the button (12) away from the circuit board (14). A plurality of angled surfaces (84, 92, 126, 172) on the movable assembly (100) cooperate to cause the movable assembly to rotate about the axis (22) when the button (12) is manually depressed toward the circuit board (14).
