3*4 Tact Switch

3*4 mini light touch tactical switches are compact and well-designed, and can meet the needs of various small electronic devices for switching performance. When purchasing and using, it is recommended to choose the 

appropriate switch model and specification according to the specific application scenario and needs.

Here is some detailed information about the structure of the 3*4 mini tact switch:

1. Overall structure of mini switch

The 3*4 mini  tact switch usually consists of shell, base, contact, reed (shrapnel), button and other parts. These parts work closely together to realize the function of the switch.

2.the shell and base of the 3*4 tap switch

Shell: The shell of the switch is usually made of plastic or metal, which is used to protect the internal components of the switch and at the same time provide an aesthetic appearance. The compact size of the housing 

makes it suitable for installation in electronic devices with limited space.

Base: The base is the supporting part of the switch and usually forms the main body of the switch together with the housing. The base is provided with key components such as contacts, reeds, etc. and provides pins or pads 

for connection to the circuit board

3. Contacts and Reeds of 3*4 touch switch

Contacts: Contacts are the key part of the switch and are used to make contact with the reed when the switch is pressed to close the circuit. Contacts are usually made of metal, which has good electrical conductivity and wear 

resistance.

Reed (Shrapnel): The reed is the elastic element of the switch. When the pushbutton is pressed, the reed deforms to bring the contacts into contact with the reed. When the button is released, the reed returns to its 

original shape and the contacts are separated from the reed, thus breaking the circuit. The material and shape design of the reed has a significant impact on the performance and life of the switch.

4. Pushbuttons of 3*4 tactile switch

Pushbutton: The pushbutton is the part of the switch that the user interacts with, and is usually set on the switch's housing. The shape, size and material of the button can be customized according to the user's needs.

 When the button is pressed, it pushes the reed to close the contacts; when the button is released, the reed returns to its original state and the contacts are disconnected.

5.Other structural features

Sealing technology: some 3*4 mini light touch tactical switches use sealing technology, which is waterproof, oil-proof and anti-static, suitable for applications in harsh environments.

Dust protection measures: Although the switch itself does not have a hermetically sealed construction, the impact of dust on the switch's performance can be minimized by adding a dust cover to the exterior or taking 

other dust protection measures.

Pins or pads: The pins or pads of the switch are used to connect to the circuit board to realize the electrical connection of the switch. The number and layout of pins or pads can be customized according to user 

requirements.
