pressing force against the second movable portion 33 is released the second normally open contact 35 is separated from the second normally open fixed contact 32 with the snapping motion and the second usually opening fixed contact 32 is electrically insulated from the second normally closed fixed contact 31 with the result that it is opened in switching as mentioned above a clicking sound and a touching sensation are made by the snapping motion of the snap plate as shown in fig6 these clicking sound and touching sensation by the snapping motion of the snap plate are more clearly generated by including a bent folding line on each boundary portion between both longitudinal end portions of each second normally closed contact 34 and each short circuit portions 37 as illustrated in fig3 and 7 each second switch 3 is disposed on a plurality of peripheral portions positioned at regular intervals from the first switch 2 namely the second switches are disposed at four points around the first switch 2 at intervals of 90 u00b0 moreover each second movable portion 33 of the four second switches 3 is disposed so as to define a longitudinal direction l cf fig6 of the second normally open contact 35.
