Some differences between light touch switches and film switches

The cost and price of the light touch switch are relatively low, and there will be no big price adjustment due to the fluctuations of raw materials in the market. The relative price of membrane switch is high, the volume is large, and the price of raw materials is greatly affected.

Light tact switch and membrane switch are functional switches. Light touch switch can be connected by gently pressing the switch button when used, and the switch can be disconnected when the hand is released. Its internal structure is realized by the force of metal shrapnel. Membrane switch is a kind of its own with a line key, usually the top is composed of a PET or PC and so on material the panel with the text or pattern, the lower is conductive lines, form the middle layer is analog switch and isolation effect of the double-sided adhesive made from PET material, the bottom part is usually a PET material contact and connection lines. Press the key part of the surface with the finger, the key contact and the contact of the lower part of the corresponding part of the contact and the formation of current connection.

Light touch switch small size, belongs to the standard parts, size and related parameters should be combined with industry standards, color is relatively simple; The membrane switch can be customized according to customer requirements, different sizes, appearance and color, etc., more convenient to use, flexible membrane switch good flexibility, closed structure and waterproof structure, better adaptability to the environment.

Light touch switch can not produce function independently, must be used with PCB board, to form a complete open control system; Thin film switch is the panel, switch, conductive line integration together, can form a complete control system, can provide customers with an overall switch solution.
