What is the difference between Membrane Keypad and touch switch?

Due to the breakthrough in technical materials, Membrane Keypades have made great progress in the market in terms of waterproof, insurance, reliability and other performance. In addition, due to the ease of installation and declining profitability of Membrane Keypades, they have gradually begun to replace those applications that do not have touch switches. So what's the difference between a Membrane Keypad and a touch switch?

Touch switch small size, standard. The scale and relevant conditions of a joint venture shall be prescribed by the joint venture. Membrane switch can be customized according to the requirements of the owner's size, appearance and color, the use of more convenient, sensitive membrane switch hard, open structure and waterproof structure, better adaptability to working conditions.

Membrane Keypad

The cost and price of the touch switch are relatively low, and because of the stability of the raw materials on the market, the price has not adjusted too much. The membrane switch has high price and large volume, and the reaction volume is large due to the high price of raw materials.

Touch switch and Membrane Keypad are functional switches. A light touch of the switch can be turned on by silently clicking the switch button, which can be disconnected when the switch is released. Its internal structure relies on the elastic movement of the metal shrapnel force to realize the switch.

The Membrane Keypad is a navigation line button of its own, the top is usually composed of a pet or PC material panel with text or pattern, the lower thermal conductivity is the line, the center layer segregation is to mimic the switch pattern and the pet function material double-sided tape, the bottom is generally in contact with the pet material and the line. When pressing the key position of the surface layer with the finger, the key contact should contact the upper position to form direct current.

Membrane switch and other professional, it is a flat button, the name collocation is familiar to everyone, the control panel of many facilities are used membrane switch, it is widely used in electronic communication, electronic measuring instruments, light industry, medical facilities, light industry, bus smart toys, household appliances and other fields.

The Membrane Keypad is a multi-layer (solid) type (lockless) key switch composed of a fixed inertial insulated data layer. It integrates key, marker, dashboard and other functions in one.

Membrane Keypades have beautiful characteristics, long service life, simple structure, easy installation, good feeling to use, small space, etc., widely used in all walks of life, small to high-tech household appliances, gradually replaced a part of the light electric door market, is a large market share.

The basic task principle of the film is as follows: when the back plate is not pressed down, the plastic Membrane Keypad is in the general form, and the upper and lower contacts are disconnected, and the isolation layer acts as an isolation effect on the upper and lower lines.

When pressing the film plate, the contact of the upper channel deforms downward and coincides with the lower channel, making the channel conductive. When switched on, the channel sends a signal to the internal connected instrument, thus completing its corresponding performance. When the finger is held, the upper access contact springs back, access is cut, and the loop triggers a degree signal.
