About this product
A 14 mm metal snap dome with four legs, used as the tactile element in pushbutton and keypad assemblies. When pressed, the centre of the dome collapses and bridges the contacts on the PCB to close the circuit, then springs back to give a crisp click. The listing cites a stable click ratio and a long service life.

Frequently asked questions
Does this dome work by itself as a switch?
No. It is the switching element only. It needs a PCB with matching contact pads and a button or keypad structure to press it.
What are the four legs for?
The legs anchor the dome to the PCB pads and hold it in position during assembly and soldering.
