The cost and price of light touch switches are relatively low, and there is no major price adjustment due to market raw material fluctuations; while membrane switches are relatively expensive and bulky, and are greatly affected by raw material prices.
Tact switches and membrane switches are both functional switches. Tact switches can be turned on by lightly pressing the switch button when in use. The switch can be turned off when the hand is released. Its internal structure is made of metal shrapnel. It is switched on and off by being forced to bounce.
Membrane switch is a button with its own circuit. Usually the top layer is a panel with text or pattern composed of PET or PC, etc., the lower layer is a conductive circuit, and the middle layer is in the form of an analog switch and acts as isolation. Double-sided tape made of PET material, the lowermost part is usually the contacts and connection lines on the PET material. When you press the button on the surface with your finger, the button contacts are in contact with the corresponding parts of the contacts on the lower layer to form a current connection.
