技术领域technical field

本发明关于一种薄膜开关电路(membrane switch circuit)以及使用该薄膜开关电路的按键(keyswitch)，且特别是有关于一种具有一环形开口(annualaropening)的绝缘层(annualar opening)，并且该环形开口能协助一弹性元件(deformable member)准确地粘合至该环形开口的薄膜开关电路以及使用该薄膜开关电路的按键。The present invention relates to a membrane switch circuit (membrane switch circuit) and a button (keyswitch) using the membrane switch circuit, and in particular to an insulating layer (annualar opening) with an annular opening (annualar opening), and the annular The opening can assist a flexible member (deformable member) to be adhered accurately to the membrane switch circuit of the annular opening and the key using the membrane switch circuit.

背景技术Background technique

键盘是目前最普遍的输入装置，其可以应用在各种电子设备，如家用电脑、笔记本电脑、个人数字助理或其他类似电子设备。由于市场上对于键盘有大量的需求，所以利用最低的成本，快速制造大量的键盘，并且保证产品的高良品率以及高品质，是各家厂商的重要目标。The keyboard is currently the most common input device, which can be applied to various electronic devices, such as home computers, notebook computers, personal digital assistants or other similar electronic devices. Since there is a large demand for keyboards in the market, it is an important goal of various manufacturers to quickly manufacture a large number of keyboards at the lowest cost and ensure a high yield and high quality of products.

在薄膜式键盘按键的制造过程中，会将一弹性元件粘合至一薄膜开关电路的一绝缘层上。目前一般的作法是先将粘合剂(adhesive)直接涂在该绝缘层上，再将该弹性元件借由该粘合剂粘合至该绝缘层上。In the manufacturing process of membrane keyboard keys, an elastic element is bonded to an insulating layer of a membrane switch circuit. The current general practice is to directly coat the adhesive on the insulating layer first, and then bond the elastic element to the insulating layer by the adhesive.

然而，因为绝缘层表面平坦，常常导致弹性元件在粘合过程中容易任意滑动，进而造成粘合位置的误差，无法达到精准的定位。此外，由于绝缘层表面平坦，涂于其上的粘合剂可能会任意流动，更增加了定位弹性元件粘合位置的困难度。在无法妥善解决上述问题的情况下，往往提高了制造成本，同时产品良品率以及品质也受到相当程度的影响。However, because the surface of the insulating layer is flat, it is often easy for the elastic element to slide arbitrarily during the bonding process, thereby causing errors in the bonding position and failing to achieve precise positioning. In addition, since the surface of the insulating layer is flat, the adhesive applied thereon may flow randomly, which further increases the difficulty of locating the bonding position of the elastic element. If the above-mentioned problems cannot be properly solved, the manufacturing cost is often increased, and the product yield and quality are also affected to a considerable extent.

因此，本发明的主要范畴在于提供一种薄膜开关电路以及使用该薄膜开关电路的按键，以解决上述问题。Therefore, the main scope of the present invention is to provide a membrane switch circuit and a button using the membrane switch circuit to solve the above problems.
