PROBLEM TO BE SOLVED: To provide a press switch capable of well sustaining operability or durability of a reverse plate, without fear of short-circuiting and easy to manufacture. SOLUTION: The press switch 1-1 includes an insulation substrate 10, a center contact point pattern 50, a first pull-out pattern 60 pulled out from the center contact point pattern 50, an outer peripheral contact point pattern 70 surrounding the center contact point pattern 50 and having a gap part 73 at and around the first pull-out pattern 60, and a reversing plate 90 mounted to be contacted with the outer peripheral contact point pattern 70. Both of the center contact point pattern 50 and the outer peripheral contact point pattern 70 are formed on an insulation layer 20 formed on the insulation substrate 10, and also, a notch part 21 formed by notching the insulation layer 20 is provided on the insulation layer 20 placed at the gap part 73 of the outer peripheral contact point pattern 70, and the first pull-out pattern 60 is passed through the notch part 21.
