A robust 90 mm buzzer with a scissor mechanism evenly distributes pressure across the entire operating surface. As a result, theBuzzer reliably triggers even when operated at the edges. This button has a much better tactile feel compared to most commercially available mushroom buttons. Additionally, it is more space-saving with a height of only 30mm and looks much better on a table.

The design is so robust that theBuzzer can also be used as a foot switch.

The design consists of only 4 parts and does not require any additional mechanical components. The only necessary element is a standard 16A microswitch.

The LED version utilizes a 16-LED ring with 16pcs WS2812 LEDs (available from Chinese suppliers for a few dollars).

Have fun! 🎉
