Abstract

The invention provided a push-on switch of two stage operation in which a first and a second switches are switched on by pushing operation, in which a movable contact plate is fixed to a circuit board by a pressure-sensitive adhesive tape without deteriorating the operation property of the movable contact plate made of a metallic spring plate. A spacer 20 is arranged at the surroundings of a movable contact plate 1 on a circuit board 8, and by this spacer 20, a continuous or a non-continuous tape pasting surface 21 which is lower than the crown part of a central plate part 3 and higher than a surrounding plate part 2 is formed on the surroundings of the movable contact plate 1, and pasting of the pressure-sensitive adhesive tapes 9, 19 on the surrounding plate part 2 is prevented. The adhesive tape 19 has non-pasting parts 27, 27 at least at a location opposed to the surrounding plate part 2 between the connecting portion to the connecting plate parts 4, 4 of the surrounding plate part 2 of the movable contact plate 1, and thereby, even if the adhesive tape 19 contacts the surrounding plate part 2 at the switching on of the first switch, it is prevented that the adhesive tape 19 is pasted to the surrounding plate part 2.

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...
