Abstract
To provide a method of manufacturing an electrical contactor including a volute spring structure extending in upward and downward directions formed integrally using a single material, having mechanical simplicity and excellent functionality, and functioning as an electric circuit achieving connection without loss. The present disclosure is intended for a method of manufacturing an electrical contactor made of a plate-like member having electrical conductivity, comprising: (1) a first step of forming the plate-like member into a barrel shape by winding the plate-like member in a spiral pattern; (2) a second step of compressing the plate-like member formed into the barrel shape from a vertical direction until the plate-like member assumes a volute shape with an upper spiral structure and a lower spiral structure overlapping each other; and (3) a third step of forming a volute-shaped electrical contactor by performing predetermined hardening treatment on the plate-like member temporarily assuming the volute shape as a result of the second step.
