1. The shrapnel of the membrane switch button kit needs to be placed properly. There can be no offset, otherwise it will affect the operation failure of the keypad.
2, the problem of color: the proportion of ink modulation is the main cause of color deviation, there is a strict color requirements, color range is small.
In terms of the cost of controlling the company, to achieve a very small range of colors, the cost to be paid is extremely high, the cost of the product is increased, and the unit price of the product is also correspondingly increased. It is also difficult for the customer to accept it. The range of color needs to be within a reasonable range.
3, the button bulge position, you need to open the mold to a suitable location, otherwise it will affect the appearance of the button. Adhesive is not sticky, in addition to the selection of raw materials, but also to confirm the shape of a good prototype, if the prototype has a groove you need to select a good quality adhesive, adhesive back to the right choice.
Tactile switches are small in size and are standard parts. Sizes and related parameters must be combined with industry standards and the colors are relatively simple. Membrane switches can be ordered in different sizes, appearances and colors according to the requirements of customers. It is more convenient and flexible to use. The membrane switch has good flexibility, closed structure and waterproof structure, and has better adaptability to the environment.
The tact switch cannot function independently and must be used in conjunction with a PCB circuit board to form a complete open control system. Membrane switches integrate panels, switches, and conductive circuits to form a complete control system. Can provide customers with a whole switch solution.
In general, the keys of the membrane switch only use color to express the position, shape, and size of the key body. In this way, the accuracy of the operation can only be recognized by the operator's visual sense, because there is no proper feedback information indicating whether the finger is pressed in the effective range of the switch to make the switch act, thereby affecting the confidence of the whole machine monitoring and the speed of the operation.
However, the key switch of the membrane switch is more visually enhanced, not only can accurately give the scope of the key body, improve the recognition speed, make the operator's touch more sensitive, but also enhance the appearance of the product's decorative effect. Therefore, the button bulging is increasingly welcomed by users and manufacturers.
Hard membrane switch means that the pattern and circuit of the switch are made on a common printed circuit copper clad board.
Hard membrane switch Advantages: Easy access to materials, stable process, low resistance, and direct soldering of certain components in the circuit on the back side. In the case of a small area, the hard liner layer can be omitted. Hard membrane switches generally use metal guides as conductive labyrinth contacts, and therefore have a better handle.
Disadvantages of the rigid membrane switch: It is convenient to install the flexible membrane switch in the whole machine. It is often necessary to solder the plug and lead the wire through the flat cable. Information Feedback of Hard Membrane Switch In addition to beep signals and LED indications, metal touch springs are commonly used.
