Capacitive Membrane Keypad With 3M467 Adhesive tactile dome button
Capacitive Membrane Keypad feature-Economic benefit
Switch production is made at one time according to the final membrane switch design. The connection of the switch group and the lead-out of the switch circuit have been screen printed at one time by special printing methods. In terms of the cost of switch processing, the cost is lower than that of discrete parts especially for large-scale manufacture. In terms of the overall cost of the user, it also has these economic advantages.
Firstly, there is no need of punching and fixing, which greatly reduces the assembly process. Secondly, the connection of the switch group does not need to be welded one by one. It can not only save time but also avoid the hidden trouble caused by welding quality. Thirdly, there is no need to configure the panel, dig holes and open windows on the display part of machine interfaces. At the same time, due to the innovative structure and strong sense of the times, it can improve the credibility and market competitiveness of products. of course, the added value generated is still obvious.
