Piezoelectric Switch

What is a piezoelectric switch?

Piezoelectric switch is a kind of electrical switch based on piezoelectric effect, which belongs to a kind of inductive switch. ABILKEEN piezo switch can be used underwater 1 meter deep,it’s IP68 waterproof degree.We developed high-precision stainless steel metal waterproof push button switch.

Working principle of piezoelectric switch:

Piezoelectric switch is a self-electric sensor composed of piezoelectric elements. The piezoelectric element is deformed by external force in a certain direction, and the phenomenon of charge polarization is generated internally. The charge of opposite polarity and equal size is generated on the upper and lower surfaces of the element, and the amount of charge is directly proportional to the pressure. When the direction of the external force changes, the positive and negative polarity of the charge also changes. When the external force is removed, the element returns to the original uncharged state, which is called the piezoelectric effect.

Application of piezoelectric switch

Piezoelectric switches are widely used in medicine,marine, car wash,shower,mining, food production and other industries.

ABILKEEN piezo switch can be only used less than 24V, waterproof and push type.12V led illuminated is well received in USA,European countries. Mounting diameter from 12mm to 30mm are optional.Welcome to visit us!
