SWITCH AND METHOD FOR MANUFACTURING SWITCH

Japanese Patent JP2017050089

A

PROBLEM TO BE SOLVED: To enhance waterproofness of a switch to be mounted on electronic equipment.SOLUTION: A case 2 is formed of a first resin R1. A first fixed conductive member 3 and a second fixed conductive member 4 are supported by the case 2. A movable conductive member 5 changes an electric connection state of the first fixed conductive member 3 and the second fixed conductive member 4. A first waterproof portion 8 and a second waterproof portion 9 are formed of a second resin R2 having higher adhesion to the first fixed conductive member 3 and the second fixed conductive member 4 than that of the first resin R1. Each of the first fixed conductive member 3 and the second fixed conductive member 4 has first portions 31, 41, second portions 32, 42, and third portions 33, 43. The first portions 31, 41 are arranged in a recess 21 of the case 2 together with the movable conductive member 5. The second portions 32, 42 are exposed to the outside of the case 2. The first waterproof portion 8 surrounds a third portion 33 positioned between the first portion 31 and the second portion 32. The second waterproof portion 9 surrounds the third portion 43 positioned between the first portion 41 and the second portion 42.SELECTED DRAWING: Figure 4
