Piezo switches, also referred to as piezoelectric switches, are a unique type of touch switches that use the piezoelectric effect to convert mechanical pressure into an electrical signal. These touch-sensitive switches feature a tactile button or surface that activates when pressed, transferring pressure to the built-in piezoelectric element. A piezo touch switch differs from mechanical switches that rely on physical contacts (moving parts) to complete a circuit. Piezoelectric switches integrate piezoelectric panels, allowing them to respond and stabilise when subjected to mechanical stresses. Additionally, these electronic switches are known for their durability, resistance to wear and tear, sealed design, high sensitivity, and efficiency.

Common Types of Piezo Switches:
Piezo touch switches are classified into various types based on their mounting configurations, actuation types, and detection mechanisms, such as:
- Momentary Piezo Switches – These switches generate a signal only when pressed and return to their original state when released. Think of the doorbell button.
- Latching Piezo Switches – A latching piezo switch requires one press to activate and a second press to deactivate, similar to a light switch.
- Surface-Mount Piezo Switch – A surface-mount piezo switch easily integrates into PCBs and is compact, making it ideal for applications with limited space.
- Capacitive Piezo Switches – These switches detect changes in capacitance caused by touch or proximity, offering a contactless operation.
- Thru-Hole Mount Piezo Switch – A through-hole piezo switch is a traditional design that allows easier integration into PCBs.
- Tactile Dome Piezo Switches – These switches provide physical click feedback when pressed.
Typical Applications of Piezo Switches:
