Which Snap Domes Are Suitable for PCB Boards as Switches?

Snap domes, also known as metal domes, are critical components in electronic switches and are widely used on printed circuit boards (PCBs). But with a variety of options available, which snap domes are the most suitable for your PCB board as switches? The answer is that nearly all types of snap domes can work, but the selection depends on the specific requirements of your end product.

Four-Leg Snap Domes: The Preferred Choice for Membrane Keypads
One of the most common types of snap domes used for membrane keypads is the four-leg snap dome. These domes are popular because they offer an excellent tactile click feel, which enhances the user experience. Products like mobile phones and various electronic devices often use four-leg snap domes due to their strong feedback and ability to perform well in limited space.

Round Snap Domes for Small Spaces
For smaller devices like mobile phones, round snap domes are usually preferred. Their compact design allows them to fit neatly within constrained spaces while still providing the required responsiveness and durability. If space is a concern, round snap domes could be the perfect solution for your project.

Triangle Snap Domes: Ideal for Medical Devices
In the medical field, specialized applications may require unique dome designs. For instance, triangle snap domes with legs are often used in medical devices such as electrosurgical (ESU) pencils. These domes provide a distinct click feeling and are specifically designed for use in equipment that requires high reliability and precision.
