Problems solved by technology

In addition, even if the gap between the patterns on the switching side can be reduced by improving the machining accuracy of parts, there is still a problem that it is difficult to stably realize the switching operation of continuous conduction every time it is operated.

Abstract

A multi-point switching apparatus includes a continuous common pattern formed on a contact circuit board, equally spaced to-be-switched patterns, and a slider that is brought into sliding contact with both the common pattern and one to-be-switched pattern. The slider is moved to make a switchover in succession. The slider includes a first sliding part and second sliding part that are elastically deformable individually. Each to-be-switched pattern includes a first pattern part placed so as to be brought into sliding contact with the first sliding part and a second pattern part placed so as to be brought into sliding contact with the second sliding part. The first pattern part and second pattern part are electrically connected to each other for each of the to-be-switched patterns. While any of the first sliding part and second sliding part is in a space, the other is in sliding contact with the to-be-switched pattern.

Description

technical field [0001] The present invention relates to a multi-point switching device capable of stably performing a switching operation of continuous conduction. Background technique [0002] A multi-point switching device that selectively conducts a slider to one of a plurality of switching side patterns is used in various fields. For example, Patent Document 1 discloses a multipoint input switcher suitable for switching input signals. [0003] Figure 9 It is a schematic diagram of the conventional switch 100 described in patent document 1. Figure 10 It is a schematic diagram of the multi-point input switcher 200 described in patent document 1. [0004] In the conventional switch 100, a continuous common-side pattern 122 and a plurality of intermittently-shaped switching patterns 123 are formed in parallel on a substrate. 123 brushes (sliders) 124 in common sliding contact. By moving the brush 124 to conduct one of the plurality of switching side patterns 123 , the ...
