Title:
PCB TACT SWITCH
Document Type and Number:
WIPO Patent Application WO/2012/015184
Kind Code:
A2
Abstract:
The present invention relates to a PCB tact switch, and more particularly, to a PCB tact switch having excellent water resistance because same does not have holes on the top and bottom which are open to the outside, capable of preventing erroneous operation through improved contact point safety, and capable of preventing product disengagement through improved fixing strength by being soldered to a substrate. The PCB tact switch of the present invention comprises: an insulation member (100) forming an insulator in a thin plate-shape through which electricity does not pass; an upper conductive substrate (300) formed of a conductor through which electricity may pass, covering the upper surface of the insulation member (100), and including a central contact point terminal (320) and an external contact point terminal (330) by means of a disconnecting portion (310); a lower conductive substrate (400) at the lower surface of the insulation member (100), having an insulation adhesive film (200) deposited on the upper portion thereof, and electrically connected with the upper substrate (300) by means of a through-hole (410); a metal dome (500) which is resiliently deformed by the click from a user, and which electrically connects or disconnects the upper conductive substrate (300) and the lower conductive substrate (400); an insulative film as an insulation cover(600) entirely covering the top portions of the upper conductive substrate (300) and the metal dome (500) and protecting the insides thereof; and an insulative solder mask (700) bonded to the undersurface of the lower conductive substrate (400) and covering the portions with an insulator, except for those requiring soldering, wherein a receiving slot (360) is formed by a receiving slot (110) defined through the insulation member (100) and the insulation film (111), and the metal dome (500) is disposed within the receiving slot (360).
