The structure of thin film tactile switch: superior performance makes life better

Thin film tactile switch is a common electronic switch product, with superior performance that can make life better. It can be controlled with just a gentle touch. What is the structure inside the thin film tactile switch? What kind of structure makes the product so popular?

The thin film tactile switch includes four aspects, among which the surface is a surface adhesive layer. The surface adhesive layer is used to connect the circuit layer by layer with surface adhesive, so as to seal and connect. Afterwards, there is an upper circuit board and a lower circuit board, which are actually the upper and lower layers of the circuit. When the switch is pressed, it will touch the lower layer or return to the upper layer, playing the role of disconnection and connection. The back adhesive part of the product is made of ordinary double-sided adhesive or 3m adhesive, or waterproof adhesive, which can maintain a good user experience during use. The interlayer of the product has insulation properties, mainly based on hand feel and sealing.

The basic thickness of thin film tactile switch material is below 0.25mm, which is a layer of thin film. In terms of thickness selection, it generally depends on the size. If the material is too thick, the hand feel will be poor, and if the material is too thin, the rebound will not be very obvious. Therefore, suitable materials need to be used for design and processing. This type of switch product is widely used and can be applied in many fields, such as industrial control, medical equipment production and research and development, automotive manufacturing, and so on. The available space is large, and the cost-effectiveness of the product is also high.

Thin film tactile switches are a great choice for switches, and their superior performance has been widely recognized by designers. They can be widely used in many fields and belong to a type of switch product with a long service life, waterproof, and oil resistant properties.
