Abstract

A switching device and a remote control transmitter using the switching device are provided. In the switching device, a driving body rotating in conjunction with an operation body is provided. This rotation of the driving body provides an electrical contact or separation of a switch. A rotation of the operation body causes a great number of electrical contacts and separations of the switch. The operation as described above provides fine detection of an operation angle of the operation body to provide detection of the operation position with a high accuracy.

Claims

1. A switching device comprising:

an operation body capable of rotating;

a driving body rotating in conjunction with the operation body; and

a switch for providing an electrical contact or separation in accordance with the rotation of the driving body,

wherein the switching device detects an operation position of the operation body based on the electrical contact or separation of the switch.

2. The switching device according to claim 1, wherein the switch is provided at an inner periphery of the driving body.

3. A remote control transmitter comprising:

a switching device including;

an operation body capable of rotating;

a driving body rotating in conjunction with the operation body; and

a switch for providing an electrical contact or separation in accordance with the rotation of the driving body, and

a control apparatus connected to the switch of the switching device,

wherein the switching device detects an operation position of the operation body based on the electrical contact or separation of the switch, and

the control apparatus transmits a remote control signal based on the electrical contact or separation of the switch.
