  • Two-stage movement seesaw switch apparatus
    Patent number: 6750406
    Abstract: A seesaw switch apparatus includes a manipulation knob which is tiltably supported, an operation plate which has an approximately L-shape in a plan view and is pushed and driven by the manipulation knob by way of a driver, first and second push switches which support both ends of the operation plate, and a third push switch which supports a bend of the operation plate. The driver is brought into contact with a portion of the operation plate closer to the first push switch than the third push switch, and the driver is brought into contact with a portion of the operation plate closer to the second push switch than the third push switch. The operation plate sequentially operates the first and third push switches in response to a descending amount of the driver and also sequentially operates the second and third push switches in response to a descending amount of the driver.
