Piezoelectric button
Piezoelectric push button switches are typically constructed from piezoelectric materials and electrodes. When external pressure or stress is applied to these materials, charge separation occurs, leading to a voltage change in the circuit. This voltage change dictates the state of the switch. Piezoelectric push button switches excel in touch or pressure control, capable of opening and closing circuits without any mechanical contact. They offer several advantages, including rapid response times, extended lifespans, immunity to mechanical wear, resistance to vibrations, and high waterproof ratings up to IP68. Due to these attributes, they find extensive application in environments or scenarios with stringent reliability requirements, such as the chemical industry, electric power sector, petroleum industry, automotive industry, aerospace, medical equipment, and other specialized fields.
