ABSTRACT:
A two-step push-on switch sequentially operates first and second switches via a movable contact plate configured by a metal plate spring and fixed by an adhesive tape onto a circuit board. A spacer is placed around the movable contact plate. A continuous or discontinuous tape-sticking face is lower than the top of a center plate portion and higher than a peripheral plate portion due to the spacer around the movable contact plate, thereby preventing the tape from sticking to the peripheral plate portion. In the tape, non-adhesive portions are formed in places opposing to parts of the peripheral plate portion of the movable contact plate excluding at least the connecting portions with the connecting plate portions respectively. When the adhesive tap makes contact with the peripheral plate portion during operation of the first switch, the adhesive tape is prevented from sticking to the peripheral plate portion.
