8b is a coil spring for restoring the switch member 5 to a fixed position.

The switch device configured in this way includes a switch member 5
When either end is pressed against both ends of the upper surface, the switch member 5 rotates about the rotation axis, and the operating shaft 4a
Alternatively, 4b is pushed downward, thereby performing a switching operation.

Then, when the pressing force on the switch member 5 is released, the switch member 5 releases the coil spring lla.

It is restored to its original position by the elastic force of 8b.

That is, the switch device shown in FIG. 7 selects one type of signal from two different types of signals by pressing one of the operating ends of the pressing surface of the operating button. In order to select the three types of signals separately, it is necessary to use a switch device using a slide mechanism or a toggle mechanism, which does not necessarily provide good operability. In order to be able to select the signals separately and to select two of the three types of signals, it was necessary to use a switch device with more contacts or a plurality of switch devices.

Problems to be Solved by the Invention The present invention has been made in view of the above problems, and in order to reduce the number of switch devices and improve operability.
To provide a switch device having a switching function capable of selecting three different types of signals separately or simultaneously selecting two types of signals among the three types of signals depending on the method of pressing an operation button of the switch device.

Means for Solving the Problems In order to solve the above-mentioned problems, the switch 'AW of the present invention has a rotation axis and a rotation in a first direction about the rotation axis to open/close or close the first switch. a first switching section for controlling a second switch; a second switching section for opening/closing or controlling a second switch by rotation in a second direction opposite to the first rotation direction about a rotation axis; a switch member having a third switching part that opens/closes or controls a third switch by sliding the moving shaft parallel to the rotating surface; A support means for movably supporting the switch member, and a first support means for movably supporting the switch member. Second. and biasing means for biasing the third switch to a neutral position in which it is not operated.

According to the present invention, with the above-described configuration, three different signals can be selected separately or two of the three signals can be selected simultaneously depending on the method of pressing the operation button of the switch device.

As a result, by installing this switch device, it is possible to reduce the number of switch devices and improve operability.

Example Embodiments of the present invention will be described below with reference to the drawings.
