<p>PROBLEM TO BE SOLVED: To provide a reverse plate and a push switch capable of improving durability and click feeling, and of being miniaturized.SOLUTION: A reverse plate 1 is configured so that the outer peripheral part thereof is formed as a truncated cone-like skirt part 30 by diaphragm processing of a thin plate with elasticity, and so that the inside central part thereof is formed as a dome part 20 expanded upwards. A curvature radius of a pair of outer peripheral parts 31-2 laterally opposed to each other among an outer periphery 31 of the reverse plate 1, is set to be larger than that of the other outer peripheral part 31-1. The outer peripheral part 31-1 with a smaller curvature radius is used as a ground part to a circuit board 250 on which the reverse plate 1 is placed, and the outer peripheral part 31-2 with a larger curvature radius is used as a non-ground part not grounded (or lightly touched) with the circuit board 250.</p> |
