Abstract

The invention provides a membrane switch and a line setting method thereof. The membrane switch comprises two films, a touch-control circuit and a soft flat cable, wherein the two films have two corresponding internal surfaces, the touch-control circuit is formed at the corresponding internal surface of film and has a plurality of touch-control portions and a leading-out terminal, and two corresponding touch-control portions are pressed and are switched on to transmit signals to the leading-out terminal. The soft flat cable has a junction portion electrically connected to the leading-out terminal to form the end of a thread, wherein a jumper is not disposed at the touch-control circuit corresponding to a film department but disposed in the soft flat cable. The invention not only makes the film simplified and the thin film design can be adapted to different customers' demands.

Description

technical field [0001] The invention relates to a switch and a circuit setting method, in particular to a membrane switch and a circuit setting method thereof. Background technique [0002] Membrane switch (Membrane Switch) uses a plurality of touch portions (touch portions) respectively located on the inner surfaces of two opposite thin films (thin film) to make the two corresponding touch portions contact each other after being squeezed by external force to make the circuit Conduction is formed, and then the desired switching action is achieved to generate a signal. Combining an array of membrane switches and connecting them through a circuit can become a set of input devices, which are commonly found in flexible printed circuit boards used in notebook PC keyboards. [0003] figure 1 It is a schematic diagram of a known membrane switch used in a notebook computer keyboard with a wire head. Generally speaking, if figure 1 The known membrane switch 10a with outlets shown...
