Problems solved by technology

[0004] In the case of applying the technical matters described in JP-A No. 2003-77368 and the like to the two-stage action push switch described in JP 7-53234 and the like to form an ultra-thin two-stage action push switch, The adhesive tape attached to the peripheral plate portion of the movable contact plate deteriorates the operating characteristics (elasticity) of the expanded shape and contracted shape of the peripheral plate portion, causing the first stage of pressing when the first switch is turned on. Increase in load and sluggishness (deterioration) of the feel of the first step when the first switch is turned on

Abstract

The present invention is as follows. That is, in the push switch of the two-step action of continuously turning on the first and second switches by pressing and operating the first and second switches, the movable contact plate formed by the metal leaf spring is not degraded. The movable contact plate is fixed on the circuit substrate with an adhesive tape. A liner (20) is arranged around the movable contact plate (1) on the circuit substrate (8), and the center part (20) is formed around the movable contact plate (1) by the liner (20). 3) A continuous or discontinuous tape adhesive surface (21) with a lower top portion and higher than the peripheral plate portion (2), preventing the adhesive tape (9, 19) from sticking to the peripheral plate portion (2). The adhesive tape (19) is at least opposite to the peripheral plate portion (2) between the connected portions of the connecting plate portions (4, 4) in the peripheral plate portion (2) of the movable contact pole plate (1) Non-adhesive parts (27, 27) are formed at the position, even if the adhesive tape (19) is in contact with the peripheral plate portion (2) when the first switch is turned on, the adhesive tape (19) can be prevented from sticking to the peripheral plate portion (2) up.

Description

technical field [0001] The present invention relates to a push switch with two stages of action that is continuously turned on by pressing the first and second switches. Background technique [0002] In the past, such a push switch with two stages of action is known (for example, with reference to the publication No. 7-53234), that is, in the switch housing with the first fixed contact and the second fixed contact inside, a leaf spring made of metal is arranged. Composed of a ring-shaped peripheral plate portion, a central plate portion bent upwards and a movable contact plate connecting them, the connecting plate portion is reversed to a downwardly inclined state by pressing the central plate portion , make contact with the first fixed contact (the first switch is turned on), and then, the center plate part is reversed to a downwardly protruding state, and makes contact with the second fixed contact (the second switch is turned on). [0003] In addition, there is a techniq...
