We compare several aspects from the following touch switch are: Stamping - Injection - Cleaning - Assembly - forming - test processes; while membrane switch technology mainly: screen printing - cutting - Assembly - - testing and other processes. Both the production environment requirements are high, relatively speaking, the use of higher dust levels workshop production of product quality more secure. Membrane switches require high precision, with the precise requirements of each part of the product's appearance, color is also very picky. The touch switch will require a higher degree of precision, since the parts with a direct impact on energy and feel to the product description, the product performance requirements are very high, but the appearance of the product, color as membrane switch picky.
Touch switch is relatively low cost and price, not because of market fluctuations in raw material prices have a big adjustment; while the relatively high price of membrane switch, bulky, influenced by raw material price factors. Touch switch with membrane switch belong to functional switches, touch switches are used to gently tap the switch button switch is turned on, when to let go when you switch off, its internal structure is by metal shrapnel force to achieve the flick-off. Membrane switch is an auto with line keys, usually the top are made of PET or PC material composition, etc. with text or pattern of the panel, the lower is the conductive lines, the middle layer is a form of analog switch and play a role in isolation PET material made by a double-sided adhesive, the lowermost part of the PET material is usually contacts and connecting lines. The surface of the button with a finger on the parts when the lower part of the button contacts and the contacts of the contact position corresponds to a current connection.
Touch switch small size, are standard parts, dimensions and parameters required to combine industry-standard, color is also relatively simple; while the membrane switch may upon request, made of different size, appearance and color, more convenient and flexible. Membrane switch softness, closed structure and waterproof construction, better adaptability to the environment. Tact switch can not function independently generated must be used in conjunction with the PCB circuit board in order to form a complete open control system; rather sucked membrane switch panels, switches, conductive lines together, able to form a complete control system, can provide an overall switching solutions. |
