Problems solved by technology

[0011] Therefore, as mentioned above, it is difficult to make the position of each pressing protrusion coincide with the position of each metal dome top to install the key top member. Although the cost of a new light guide plate can be saved, it is difficult to stably manufacture a light guide plate with a good click feeling. power switch button

Abstract

A metal dome sheet (10) provided with a metal dome (8) which, when elastically deformed by push operation of a key top (16) provided on a board (2), becomes electrically connected to a contact (6) and which, when the key top is released from the push operation, is restored from the deformation to break the electrical connection between the metal dome and the contact. The metal dome sheet (10) has an elastic push projection (12) for transmitting push force applied from the key top (16) side to a top section (8a) of the metal dome (8).

Description

Technical field [0001] The present invention relates to a part used in a push button switch of a portable electronic device headed by a mobile phone or a mobile information terminal device (PDA: Personal Digital Assistance), and more particularly to a metal dome sheet mounted with a metal dome (metal dome sheet) and a button switch using the metal dome sheet. Background technique [0002] With the popularization of portable electronic devices such as mobile phones and mobile information terminal devices (PDAs), push-button switches used in these portable electronic devices are also widely used. In most cases, this type of push button switch has a fixed side contact provided on the substrate, and an elastically deformable metal dome arranged to cover the contact (the metal dome serves as a movable contact ) And a key top member arranged on the upper part of the metal dome. (In the following description, the board side of the push button switch is the lower side, and the operatio...
