Method of forming contacts on slide type switch

Abstract

An objective of the present invention is to provide a sliding type switch capable of maintaining excellent contact onto a terminal plate of a contactor and improving position detection precision of an operating unit by improving contact surface pressure. The sliding type switch includes: a plurality of terminal plates (2) extended to a terminal frame (1); a movable member (4) cooperating with an operating unit such as a shift lever to be rotated with respect to the terminal frame (1); a contactor (5) slidably moved on the terminal plate (2) according to movement of the movable member (4); and a contact part (5a) slid with respect to a pair of terminal plates (2) while making contact with the terminal plates (2). The contact part (5a) of the contactor (5) makes contact with the pair of terminal plates (2) to achieve electric conducting. The sliding type switch may detect a position of the operation unit by generating an electric signal according to a relative position of the terminal frame (1) of the movable member (4). At least one contact part (5a) of the contactor (5) makes point-contact with the terminal plate (2) to be slid.

Description

technical field [0001] The present invention relates to a method of forming a contact on a slide type switch which realizes electrical conduction by contacting a contact portion of the contact with a terminal board, by generating a relative position of a movable part with respect to a terminal board The corresponding electrical signal can detect the position of the operating unit such as the shift lever. Background technique [0002] Generally, an automobile equipped with an automatic transmission is provided with a slide type switch called a so-called shift switch for detecting the position of an operating unit such as a shift lever. This slide type switch, as disclosed in Patent Document 1 and Patent Document 2, for example, is constituted to have: a plurality of terminal boards, which are extended and provided on the terminal block; movable relative to the terminal block; and a contact formed on the movable member and capable of sliding on the terminal board accompanying...

Problems solved by technology

[0006] However, in the above-mentioned conventional slide type switch, since the contact portion of the contact piece slides while being in line contact with the terminal board, there is a problem that the contact portion of the contact piece is moved against the terminal board when the movable member moves. Insufficient pressure on the contact surface when sliding upward, or tilting of the contact piece during sliding, causing one of the pair of contact parts to separate from the terminal board

As described above, if the contact part is separated from the terminal board due to insufficient contact surface pressure or inclination, etc., there will be poor electrical conduction between the contact and the terminal board, or the position detection accuracy of the operation unit will deteriorate.
