Claims

[Claims for Utility Model Registration] (1) A substrate having a first lower contact portion formed by bringing predetermined portions of a plurality of circuit patterns close to each other, and a first connection pattern provided on a part of the circuit patterns; a spacer that has a plurality of holes or grooves and is attached to the substrate so that the first lower contact portion and the first connection pattern on the substrate are exposed; A first upper contact portion and a second connection pattern are formed at positions facing the first lower contact portion and the first connection pattern, respectively, and predetermined portions of a plurality of circuit patterns are formed on the upper surface of the first upper contact portion. an electrode sheet having a second lower contact portion formed in close proximity to each other, and further having a part of the circuit pattern of the second lower contact portion electrically connected to the second connection pattern on the lower surface side via a through hole; a second upper contact part placed on the second lower contact part provided on the sheet and connected to the second lower contact part by pressing against the upper part; 1. A two-stage push button switch comprising: a resilient member that presses a second connection pattern provided on the substrate into pressure contact with a first connection pattern provided on the substrate. (2) The second upper contact portion has a structure in which elastic rubber is curved upward, and a conductive portion is provided on the back surface of the second upper contact portion at a position opposite to the second lower contact portion. The two-stage push button switch described in (1).
