We will compare the differences from six aspects: function, structure, cost price, production technology, switch size (appearance), technical level.

1. Function comparison: 

The tact switch can turn on the power with just a light touch, and it will be disconnected when you release it. The power is turned on and off by the bounce of the metal shrapnel; the membrane switch is the button on the surface that is pressed by hand, and the button contact point is with the lower layer. The corresponding part of the contact point of the contact is contacted to form a galvanic connection;

2. Structure comparison: 

Tact switches cannot be used alone, they must be used in combination with PCB circuit boards to form a complete control system; membrane switches integrate panels, switches, and conductive circuits to form a complete control independently The system can provide customers with an overall switch solution.

3. Manufacturing cost analysis: 

The cost of tact switches is relatively low compared to membrane switches. The tact switch will not produce large price fluctuations due to fluctuations in the raw material market, while the relatively high price and large volume of membrane switches are greatly affected by the price of raw materials.

4. The difference in production process: 

The process of membrane switch includes: silk screen, die cutting, assembly, testing and other processes. The process of the tact switch includes: stamping, injection molding, cleaning, assembly, molding, inspection and other processes;

5. Switch size and appearance: 

Membrane switches can be customized according to customer requirements, with different appearances, sizes, and colors, which are convenient and flexible to use; the tacth switch is relatively small in size and belongs to standard parts. The size and related parameters need to be combined with industry standards. The color is relatively single;

6. Technical requirements: 

The precision of the tact switch is relatively high, and the coordination of various parts directly affects the feel and function of the product, and has higher requirements on the performance of the product; Membrane switch is relatively more strict, it is also very important to the appearance of the product and color;
