Two-stage movement seesaw switch apparatus

A two-stage movement seesaw switch apparatus comprising:

• a manipulation knob which is tiltably supported;
• a pair of elevatable drivers corresponding to a tilting direction of the manipulation knob;
• an operation plate which is pushed and driven by the manipulation knob by way of the drivers;
• a first push switch and a second push switch which support both ends of the operation plate;
• and
• a third push switch which is arranged at a position displaced from a straight line which connects both push the first and second switches and supports an intermediate portion of the operation plate, wherein
• one of the drivers imparts a pushing force from the manipulation knob to a portion of the operation plate closer to the first push switch than the third push switch so as to make the operation plate sequentially operate the first push switch and the third push switch in response to a descending amount of the driver, and
• wherein the other of the drivers imparts a pushing force from the manipulation knob to a portion of the operation plate closer to the second push switch than the third push switch so as to make the operation plate sequentially operate the second push switch and the third push switch in response to a descending amount of the other of the drivers.
