What Type of Overlay Do Capacitive Switches Use?

Capacitive switches have become a popular alternative to mechanical switches. As their name suggests, they leverage capacitance. Capacitive switches measure changes in capacitance, and they use this information to open or close a circuit. Pressing a capacitive switch...

The Rise of Piezo Switches: What You Should Know

When researching the different types of switches, you may come across piezo. Not all switches rely on moving parts. In addition to mechanical switches, there are piezo switches. Piezo switches are essentially touch switches that feature a piezoelectric panel. The...

Panel vs Membrane Overlay: What’s the Difference?

Switches typically require a top layer. Known as an overlay, it often contains conductive contacts on the underside. Pressing a button on a switch will force these conductive contacts to touch a lower set of conductive contacts, thus completing the circuit. While you...
