12*12MM Illuminated Pushbutton

An illuminated tact button is a type of switch that is commonly used in a variety of industrial and commercial applications. The button is designed to provide a tactile feel when pressed, and it usually includes an LED illumination feature that makes it easy to see in low-light conditions. In this article, we will explore the features and specifications of a 12*12mm illuminated tact button that is commonly used in LED video processors.

Size and Shape

The 12*12mm illuminated tact button is a small and compact switch that is designed to be easily integrated into small electronic devices. It has a square shape with rounded edges, and it measures 12mm in length and 12mm in width. The button has a total thickness of around 6mm, which includes the height of the switch, the plunger, and the base.

An integrated light - emitting diode (LED) is at the core of the button's illumination system. The LED can emit various colors like red, green, blue, yellow, or white, depending on the design and application requirements. A light - diffusing mechanism is usually employed to ensure an even distribution of light across the button cap, creating a consistent and bright glow. This illumination serves multiple purposes, such as indicating the button's status (e.g., active or inactive, normal operation or error condition) or simply making the button more visible in low - light environments.

Tactile Functionality
The tactile aspect of the button is provided by a spring - loaded actuator mechanism. When the button is pressed, the actuator makes contact with internal electrical contacts, completing an electrical circuit and triggering the intended function. The spring provides a satisfying tactile "click" sensation, giving users immediate feedback that the button has been successfully activated. The force required to press the button is carefully calibrated to balance between preventing accidental activation and ensuring ease of use.

Electrical Characteristics
It is designed to operate within specific electrical parameters, including a rated voltage (usually a low - voltage DC range, like 3V to 12V) and a rated current. The electrical contacts are made of materials with good conductivity to ensure reliable circuit connections and low contact resistance. The button also has certain insulation and dielectric strength characteristics to prevent electrical failures and ensure safety.
