First Claim
1. A switch unit, comprising:
- a switch knob arranged capable of being tilted with a rotational shaft at a shaft center and provided with an automatic reset function for restoring to an original position;
a switch shaft connection shaft provided on the switch knob;
a switch shaft being moved in accordance with an inclination restoration operation as a result of connecting to the switch shaft connection shaft;
a guide rail for guiding movement of the switch shaft in a straight line; and
a tact switch, arranged capable of connection and disconnection to and from the switch shaft, for electrical connection and disconnection as a result of pressure from the switch shaft, wherein the tact switch has a region pressed from the switch shaft and constituted by a resilient member.

Abstract
A switch shaft connection shaft (24) is formed on a switch knob (22), and connected to a switch shaft (26). Therefore, the switch shaft (26) can move in response to an inclination restoration operation of the switch knob (22). Further, the switch shaft (26) has movement in the lateral direction regulated by a guide rail (17), which makes it possible to always exert pressing force vertically with respect to a tact switch (25). Moreover, a region where the tact switch (25) is pressed from the switch shaft (26) is constituted by a resilient member, which means that there is no striking noise when the switch shaft (26) strikes the tact switch (25), and it is possible to provide a switch unit that is quiet at the time of operation.
