Abstract

The present disclosure relates to a pressure-sensitive switch including a support substrate, a conductive structure provided on the support substrate, and an electrode unit disposed to face the support substrate with the conductive structure interposed therebetween. The conductive structure includes an elastic component extending to protrude from the support substrate toward the electrode unit, and an electrode layer covering the elastic component.

Description

technical field [0001] The present invention relates to a pressure sensitive switch and a method of manufacturing the same. In addition, the present invention also relates to a touch panel having the pressure-sensitive switch and a manufacturing method thereof. Background technique [0002] In recent years, various electronic devices, such as smartphones and car navigation systems, have been rapidly increasing in functionality and diversification. Along with this, it is required to also reliably operate the pressure-sensitive switch which is one of the constituent elements of the electronic equipment. Such as Figure 11 As shown, the conventional pressure-sensitive switch mainly includes a support substrate, a conductive structure provided on the support substrate, and a pressing base material provided with an electrode portion provided above the conductive structure. The electrode portion is connected to an electronic circuit of the device through a wire or the like. The...
