Introduction and application fields of different tact switch

Tact Switch is an electronic switch that triggers signals by a slight press and is often used in consumer electronics, household appliances, industrial equipment, etc. The following are the main types of touch switches produced by our company AIBEIKEN.

Standard type touch switch

Features: The most basic type, square or round, with 4 pins (2 sets of normally open contacts).

Size: Common sizes include 6×6mm, 12×12mm, etc.

Applications: Keyboard, remote control, simple control panel.

2. Surface mount Technology (SMT) touch switch

Features: Specifically designed for surface mount Technology (SMT), with flat pins, suitable for automated production.

Size: Miniaturization (such as 3×4mm, 5×5mm).

Application: Compact electronic products such as mobile phones, tablets and wearable devices.

3. Side-press touch switch

Feature: Press from the side to save top space.

Application: Ultra-thin devices (such as digital cameras, smartwatches).

4. Ultra-thin touch switch

Features: Extremely low height, suitable for ultra-thin design.

Applications: Notebook computer touchpads, foldable screen mobile phones.

The touch switch mainly serves the purposes of signal input, function control or status switching. The following are its common application fields and specific functions:

Consumer electronic products

Application equipment:

Smart phone (power button, volume button)

Remote control (key input)

Game controller (ABXY keys, direction keys)

Keyboard (Trigger switch of membrane keyboard)

Function:

Short press/long press to achieve operations such as power on/off, menu selection, and function confirmation.

Provide haptic feedback (" click "sensation) to enhance operational accuracy

2. Household appliances

Application equipment:

Microwave oven, rice cooker (control panel)

Air conditioner, fan (mode switch key)

Smart home devices (such as the start button of a sweeping robot)

Function:

Trigger preset programs (such as heating and timing) by pressing.
