Abstract

A switch includes a case, fixed electrodes, a movable electrode and a pressing member. The fixed electrodes and the movable electrode are arranged inside the recess. The pressing member is arranged so as to cover at least a part of the recess, and displaces the movable electrode from the second position to the first position by a pressing force from the outside. The pressing member includes a first bent part and a second bent part, and a deforming part disposed therebetween. The deforming part is opposed to the movable electrode with a gap in a state where the movable electrode is in the second position. The deforming part is configured to be flexibly deformed toward the outside of the case in a state where the movable electrode is in the first position in which the fixed electrodes are in a conductive state.

First claim

What is claimed is:

1. A manufacturing method of a switch, comprising:
holding a resin molded body by a plurality of dies;
pressing the resin molded body from a first side thereof using a punch to form a plastic deformed part projecting to a second side opposite to the first side;
deforming the plastic deformed part so as to project to the first side to form a first bent part and a second bent part; and
arranging a part of the resin molded body disposed between the first bent part and the second bent part so as to be opposed to a movable electrode of the switch with a gap.

2. The manufacturing method according to claim 1 , wherein
the resin molded body is formed of a material containing a thermosetting resin or a thermoplastic resin.
