In addition, at this moment, between the periphery of the inwall of above-mentioned accepting hole 1a and travelling contact 3, the space is set, this space that forms makes the space S2 between the periphery of the inwall of narrow width part of accepting hole 1a and above-mentioned travelling contact 3 bigger than the space S1 between the periphery of the inwall of the wide width part of above-mentioned accepting hole 1a and above-mentioned travelling contact 3.Like this, space S2 between the periphery of the inwall of the narrow width part of above-mentioned accepting hole 1a and travelling contact 3 is bigger, thereby, can make the 2nd thin slice 4 and the periphery of bonding part 4a the 1st thin slice 1 away from the direction in a narrow margin of travelling contact 3, therefore, make bonding and the constraint travelling contact 3 that produces obtains relaxing, can carry out more reliable rotary movement by the 2nd thin slice 4.
Then, if remove pushing of above-mentioned the 2nd thin slice 4 from above-mentioned state, then travelling contact 3 is because the elastic force of self and upward to upset, the contact portion of the following side of outer teat 3c is separated from central fixed contact 7a, and central fixed contact 7a and peripheral fixed contact 7b TURP break, become the OFF state.
At this moment, because the link direction that links the above-mentioned binding groove 1b between above-mentioned accepting hole 1a is set along the rectangular direction that is housed in the travelling contact 3 among the accepting hole 1a, therefore, during travelling contact 3 upsets, near the bonding part 4a of the 2nd thin slice 4 the narrow width part of travelling contact 3 can be attached on the insulated substrate 6, can obtain to reset reliably, can prevent that bonding part 4a from entering into contact inside simultaneously.
Like this, the thin slice of the band travelling contact of above-mentioned travelling contact 3 will be accommodated, be positioned in, and this insulated substrate 6 disposes the peripheral fixed contact 7b that contacts with the abutting part 3e of the lower end periphery 3a of travelling contact 3 and with the central fixed contact 7a's of the outer teat 3c subtend of arcuation of travelling contact 3, thereby can obtain the formation of the push-button switch of sheet type simply, the push-button switch that improves reliability, guarantees desired travel and energy miniaturization can be provided owing to above-mentioned formation.
