Switch

Abstract

This switch is composed of a contact mechanism 10 wherein the movable contact 15a of a movable contact piece 15 is made to face a stationary contact 13a so that they can be brought into contact with each other or separated from each other, a base 20 wherein the contact mechanism 10 is insert-molded, an operating lever 40 having an operating part 41 projecting toward its side from one end side and an operating rib 42 protrusively provided on its lower surface, which is slidably assembled to the upper part of the base 20, a reset spring 50 positioned on the base 20, and a cover 60 engaged with the base 20. The operating lever 40 slides against spring force of the reset spring 50 based on external force loaded to the operating part 41 of the operating lever 40 from a horizontal direction, and the operating rib 42 of the operating lever 40 pushes down the movable contact piece 15 to open and close the contact.

Description

technical field

[0001] This invention relates to switches, and more particularly to subminiature switches having a contact mechanism cut from a lead frame. Background technique

[0002] A conventional subminiature switch is a switch device that can be pressed and operated from above (for example, refer to Patent Document 1).

[0003] Patent Document 1: JP-A-2002-216589

[0004] However, in the switch device described above, the free end of the arm extending from the coil spring is used as a movable contact, and at the same time, a clip-shaped fixing device composed of a leaf spring is arranged on the moving track of the free end of the arm. contacts. The electrical connection is made by pressing the free end of the arm into the clip-shaped fixed contact. Therefore, high component accuracy and assembly accuracy are required for structural components, which not only causes trouble in production and increases in cost, but also tends to cause instability in operating characte...
