3-pin Tact Switch

The 3-pin tact switch has many advantages over other types of switches.


A 3-pin tact switch is a type of electronic switch that is typically used in various electronic devices such as calculators, mobile phones, remote controls, and other electronic gadgets. It is a momentary or tactile switch that requires physical pressure to activate or deactivate the switch. The switch is designed to have three pins, which are used to connect the switch to the printed circuit board (PCB) of the device. The switch dimensions are usually 4.5x4.5mm.

The three pins of the tact switch are located at each corner of the switch, and they are used for different purposes. The middle pin is called the common pin, while the other two pins are called the Normally Open (NO) and Normally Closed (NC) pins. The common pin is typically connected to power or ground, depending on the application of the switch. When the switch is pressed, the connection between the common pin and the NO pin is established, while the connection between the common pin and the NC pin is broken. The opposite happens when the switch is released. These switches are also available with an extra pin for LED light indication.

The 3-pin tact switch has many advantages over other types of switches. They are extremely durable and are designed to withstand repeated use over an extended period of time. They are also compact, which makes them ideal for use in small electronic devices. Additionally, they have a low profile, meaning they don't take up much space on the PCB, adding to their versatility.

the 3-pin tact switch is an essential component in modern electronics design. They are durable, compact, and easy to install, making them ideal for use in various electronic devices. They are designed to stand the test of time, and their versatility makes them a popular choice for design engineers. As technology continues to evolve, the 3-pin tact switch will remain a vital component in the world of electronics.
