Abstract

A movable contact element includes a cover sheet to which a movable contact having a dome shape is bonded and which is stacked on a top surface of a pressure sensitive conductive sheet. The movable contact element is bonded to a top surface of a substrate having a fixed contact formed thereon, thereby forming a switch. Through the construction, it is possible to obtain the movable contact element, which has a simple construction and can perform various operations, and the switch using the same.

Description

technical field [0001] The present invention relates to a movable contact body mainly used in the operation of various electronic devices and a switch using the movable contact body. Background technique [0002] In recent years, the high functionality and diversification of various electronic devices such as mobile phones and car navigation systems are progressing. With the evolution of electronic equipment, there is a demand for movable contacts and switches used for the operation of these electronic equipment, which are inexpensive and can perform various operations. [0003] use Figure 15 , to describe such a conventional movable contact body and a switch using the same. [0004] Figure 15 is a cross-sectional view of a conventional switch 150 . exist Figure 15 Among them, the switch 150 has a movable contact body 104 , a substrate 105 and a fixed contact 106 . The movable contact body 104 has a cover plate 101 and a movable contact 102 . The cover plate 101 is be...
