Touch control key

Abstract

The invention is a kind of touching control buttons for electric device, which is mainly made up of a supporting element, a switch element, a button and a soft printed wire. The supporting element is set on the printing circuit board, the switch is on the supporting element, the button is used to press switch element. The switch element has several joints, all of which are attached to the connecting cushion of soft printed wire. In order to make the PDA type electric device has the merit of palm game machine, the touching control button is set at side surface of PDA shell, the switch element can be fixed on the circuit board through supporting element, the supporting element and the circuit board are mechanicalness connection, thus the supporting element can changes direction and be fixed on the circuit board, it doesn't need to change the wire on the circuit board, it reduces the cost.

Description

technical field [0001] The present invention relates to a touch key, and in particular to a touch key used in a personal digital assistant (PDA). Background technique [0002] Information appliances are a new milestone in the electronics industry following the computer industry. The so-called "Information Appliances" (IA; Information Appliances) generally refer to devices with communication or Internet connection capabilities, as well as specific purposes such as information and entertainment. According to this definition, home information appliances allow users to connect to the Internet at any time for voice communication, sending and receiving data, and web browsing. A personal digital assistant (Personal Digital Assistant, hereinafter referred to as PDA) belongs to the category of information appliances. The most basic function of PDA is like the universal notepad that is often used in the past. All the items contained in the universal notepad, such as address book, not...

Problems solved by technology

However, it is known that the touch key 110 is fixed on the surface of the circuit board 10 and its orientation is fixed, so the touch key 110 cannot change its position as the shape of the housing 20 changes.

Even if the angle of the touch key 110 needs to be changed, for example, the horizontal viewing angle θ of 30 degrees to 60 degrees, the position of the pin 116 of the switch component 112 on the circuit board 10 must be changed, so the circuit of the circuit board 10 must be re-changed. The required manufacturing cost also increases

[0006] In addition, in terms of the current specification of the switch assembly 112, the operating life of the switching element 113 is increased, and the volume of the switch assembly 112 is relatively large; otherwise, the operating life of the switching element 113 is reduced, and the volume of the switch assembly 112 is relatively large. smaller

However, using the switch assembly 112 of the current specifications as the touch key 110 of the PDA, since the required action life of the touch key 110 must be increased to 5 million times, its volume will also increase relatively, thus occupying the entire PDA. interior space
