Embodiment Construction

[0062] will refer to 1A to 4B A description of the contact structure according to the first preferred embodiment of the present invention is given below.

[0063] First preferred embodiment

[0064] Figure 1A and Figure 1B The contact structure shown is used to detect input for rotation and depression operations in an input device (not shown). The contact structure includes a first movable contact 100 (movable contact described in the claims), a second movable contact 200, a plurality of first fixed contacts 300, second fixed contacts 400a and 400b, lead wires 510, 521 and 522 and cover 600. The first movable contact 100 and the first fixed contact 300 constitute a rotation detection device for detecting an input of a rotation operation of an annular dial in the input device. The second movable contact 200 and the second fixed contacts 400a and 400b constitute a depression detection device for detecting an input of a depression operation of a button provided in a dial pro...

Abstract

A first movable contact 100 is a ring-like metallic plate that can be rotated on a first fixed contact 300. The first movable contact 100 is provided with a base 110; first and second arms 120a and 120b continuously connected to fixable portions 112 of the base 110; and first and second sliders 130a and 130b continuously connected to the tips of the first and second arms 120a and 120b. The first and second sliders 130a and 130b are arranged in such a manner as to slide on the first fixed contact 300 on sliding tracks different from each other in accordance with the rotation of the first movable contact 100. Thus, it is possible to provide a movable contact that is capable of reducing abrasion of the fixed contact or a resistor.

Description

technical field [0001] The present invention relates to a movable contact and a contact structure provided with the movable contact. Background technique [0002] JP2001-148219A discloses a conventional contact structure constituting a rotation detection device for detecting rotation of an operating member for an input device. The contact structure includes a movable contact that rotates according to the rotation of the operating member and a plurality of fixed contacts that are annularly spaced. The movable contact has three sliders that selectively slide on the fixed contact according to the rotation of the movable contact. SUMMARY OF THE INVENTION [0003] technical problem [0004] All the sliders of the movable contacts described above are arranged to slide along the same sliding track on the fixed contacts. As a result, the fixed contacts tend to be easily worn out. [0005] The present invention has been devised in view of the above circumstances. The present i...
