1. A switching device comprising:
- an operation body arranged to rotate about a first rotary axis;
a driving body arranged to rotate about a second rotary axis in conjunction with rotation of said operation body about said first rotary axis; and
a switch for providing an electrical contact or separation in accordance with rotation of said driving body;
wherein said switching device detects an operation position of said operation body based on the electrical contact or separation of said switch;
wherein said first rotary axis is offset from said second rotary axis; and
wherein said operation body and said driving body are arranged so that rotation of said operation body through a first rotational angle results in rotation of said driving body through a second rotational angle greater than said first rotational angle.

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.

5. A remote control transmitter comprising:
-
a switching device including an operation body arranged to rotate about a first rotary axis, a driving body arranged to rotate about a second rotary axis in conjunction with rotation of said operation body about said first rotary axis, and a switch for providing an electrical contact or separation in accordance with rotation of said driving body, wherein said switching device detects an operation position of said operation body based on the electrical contact or separation of said switch, wherein said first rotary axis is offset from said second rotary axis, and wherein said operation body and said driving body are arranged so that rotation of said operation body through a first rotational angle results in rotation of said driving body through a second rotational angle greater than said first rotational angle; a control apparatus connected to said switch of said switching device; and wherein said control apparatus is operable to cause transmission of a remote control signed based on the electrical contact or separation of said switch. - View Dependent Claims (6, 7, 8, 9, 10)
