90 Degree Illuminated Tact Switch

A 6x6mm 90 degree illuminated tact switch is a type of tactile switch that has a square base with dimensions of 6mm by 6mm. The switch has a plunger that protrudes from the top of the base and is used to make contact with an electrical circuit. The switch is designed to be mounted on a printed circuit board (PCB) and has four pins that make electrical contact with the board. 

The 90 degree in the name of the switch refers to the orientation of the switch in relation to the PCB. The switch is mounted on the board at a 90-degree angle, which means that the plunger protrudes from the side of the switch rather than from the top. This orientation allows for easier access to the switch when mounted on the board and can be beneficial in certain applications.

The illuminated version of this switch has a built-in LED that lights up when the switch is pressed. The LED can be of different colors depending on the application, and the switch can be either momentary or latching. A momentary switch is one that is only active while it is being pressed, while a latching switch is one that remains in the on or off position after it has been pressed.

The defining feature of these buttons is their integrated LED illumination. Embedded LEDs light up upon button activation, providing visual feedback to users. LED illumination enhances usability, especially in low-light conditions, by indicating the button's status or function.

Illuminated right angle tact buttons feature a small and compact design, optimizing space utilization on the PCB while providing reliable performance. They contribute to the miniaturization of electronic devices and facilitate sleek and ergonomic designs.
