ある。The push button 7 is disposed so as to straddle the movable contact spring 5, and the projection 8 of the resin body 1 in which the terminals 2. Be composed. As described above, the movable contact spring 5 is formed continuously on the terminal 2a and is bent and formed with respect to the terminal 2a. The line for producing the contact spring 5 is integrated into a main line for insert-molding the metal main part B into the resin body 1 to improve the productivity. In such a case, the movable contact portion 6 formed at the tip of the movable contact spring 5 is formed so as to pinch and slidably contact the fixed contact portion 4. However, the movable contact spring 5 is not pressed by the push button 7 in a state where the movable contact spring 5 is regulated, and the movable contact spring 5 is not deformed or broken by pushing the push button 7 more than necessary. The rigidity of the movable contact portion 6 is increased by folding the fixed contact portion 4, as compared with the case where the fixed contact portion 4 is formed of a single plate. In addition, the contact pressure of the movable contact portion 6 can be easily adjusted, and the movable contact spring 5 is formed in a series on the metal main portion B.
In this case, the contact pressure can be increased even if the metal main portion B is also punched from a thin plate.
