ABSTRACT:
A switching apparatus includes a case, an operation shaft whose one end outwardly projects from inside of the case and which is provided at its central portion with a flange, a support member which supports the flange such that the operation shaft can rock and rotate, an operation knob mounted on one end of the operation shaft, a first contact which is switched when the operation knob is pushed to move the operation shaft, a second contact which is switched when the operation knob is rotated to rotate the operation shaft, and a third contact which is switched when the operation knob is rocked to rock the operation shaft. The support member comprises a first support member which supports the flange from the operation knob in a state where the operation shaft penetrates the first support member, and a second support member which is disposed inside of the first support member and which supports the flange from the opposite side from the operation knob in a state where the operation shaft penetrates the second support member. The first contact is disposed in the vicinity of the operation shaft on the opposite side from the operation knob of the support member adjacent to the second support member, and the first contact is switched by the second support member which follows the operation shaft and moves when the operation knob is pushed.
