The invention provides a movable contact for a two-step push-on switch which can realize an excellent sense and a long life period while decreasing the width, even on a flat stationary-contact forming surface of a printed circuit board, a flexible printed circuit board or the like, and also a two-step push-on switch.A movable contact has: a rectangular annular peripheral plate portion 2; an oval center plate portion 3 which is upward inflatingly curved; and a pair of connecting plate portions 4, 4 which connect an inner edge of the peripheral plate portion 2 to an outer edge of said center plate portion 3 on a center line X which is parallel to long side portions 2a, 2a of said peripheral plate portion 2. The movable contact is disposed on a flat stationary-contact forming surface of a printed circuit board, a flexible printed circuit board, or the like, and an adhesive tape 9 for fixing the movable contact is bonded from a side of the upper face, thereby configuring a push-on switch.

1. A movable contact for a push-on switch, having: an annular peripheral plate portion 2; a center plate portion 3 which is upward inflatingly curved; and connecting plate portions 4, 4 which connect said peripheral plate portion and said center plate portion together, wherein said peripheral plate portion 2 is formed into a rectangular annular shape, a whole circumference of said rectangular annular peripheral plate portion 2 is upward inclined as advancing from an outer side edge toward an inner side edge, grounding parts 2c, 2c, 2c, 2c are formed in four corners of said peripheral plate portion, bent portions 2e, 2e which upward protrude are formed in middle portions of long side portions 2a, 2a, said connecting plate portions 4, 4 are paired to connect an inner edge of the peripheral plate portion 2 to an outer edge of said center plate portion 3 on a center line X which is parallel to said long side portions 2a, 2a of said rectangular annular peripheral plate portion 2, said connecting plate portions 4, 4 are upward inclined as advancing from said peripheral plate portion 2 toward said center plate portion 3, and, by an operation of depressing said center plate portion 3, said pair of connecting plate portions 4, 4 are inverted to a downward inclined state to make contact with first stationary contacts 11, 11 which are in a same plane as a support surface of said rectangular annular peripheral plate portion 2, and a center part of said center plate portion 3 is then inverted to a downward inflated state with using said pair of connecting plate portions 4, 4 as fulcrums to make contact with a second stationary contact 12 which is in a same plane as the support surface of said rectangular annular peripheral plate portion 2.2. A movable contact for a push-on switch according to claim 1, wherein said center plate portion 3 is formed into an oval shape that is obtained by cutting away peripheral portions of a circular plate 3a with two straight lines L1, L2 which are parallel to said long side portions 2a, 2a, and a distance between which is shorter than a relative distance between inner side edges of said long side portions 2a, 2a, said circular plate having a diameter R which is shorter than a relative distance between inner side edges of said short side portions 2b, 2b of said rectangular annular peripheral plate portion 2, and which is longer than the relative distance between the inner side edges of said long side portions 2a, 2a. 3. A push-on switch wherein a rectangular recess 10 a depth of which is smaller than a height of a movable contact according to claim 2 is formed in an upper face of a printed circuit board 8 or a flexible printed circuit board 8, said movable contact is disposed on a flat bottom face of said recess 10, and an adhesive tape 9 for fixing said movable contact is bonded from a side of the upper face.4. A push-on switch wherein a movable contact according to claim 1 is disposed on a flat upper face of a printed circuit board 8 or a flexible printed circuit board 8, and an adhesive tape 9 for fixing said movable contact is bonded from a side of the upper face.5. A push-on switch wherein a rectangular recess 10 a depth of which is smaller than a height of a movable contact according to claim 1 is formed in an upper face of a printed circuit board 8 or a flexible printed circuit board 8, said movable contact is disposed on a flat bottom face of said recess 10, and an adhesive tape 9 for fixing said movable contact is bonded from a side of the upper face.6. A push-on switch wherein a movable contact according to claim 1 is disposed on a flat upper face of a printed circuit board 8 or a flexible printed circuit board 8, and an adhesive tape 9 for fixing said movable contact is bonded from a side of the upper face.
