4.5x4.5mm Mini Tact Button Switch

A mini tact button switch, also known as a tactile switch, is a small switch that can be used in a wide range of electronic applications. These switches are designed to respond to a physical force, such as pressing or holding down, to activate an action. Mini tact button switches come in various sizes and shapes, but a popular size is the 45x45mm square switch.

Functioning of Mini Tact Button Switch

A mini tact button switch consists of two components: a button and a contact. The button is typically made of plastic and has a small metal disc in the center. The contact is made of metal and is located below the button. When the button is pressed, the metal disc makes contact with the metal contact, completing an electrical circuit, and activating a function or device.
