Langir PZ22 Piezo Switch Introduction

The Langir PZ22 piezo switch is a kind of piezo switch with water resistant and water proof properties.

The IP69K is the highest level of solid and water ingress protection under the Ingress Protection rating certification.

This means that the PZ22 piezo switch is sealed against dust and water or any form of liquid.

The PZ22 Piezo Switch Features

One of the major features of the PZ22 piezo switch is its waterproof attributes.

This makes it an ideal switch to use in wet environments or where it will be exposed to water such as bathrooms, kitchens, the outdoors, or near a body of water, etc.

Also, it is touch sensitive, which means that you only need to apply ample force using your fingers to actuate the switch.

The PZ22 piezo switch has a piezo module that works as the actuation component of the switch, a compact assembly without the mechanical parts.

Lastly, it has integrated wires which remove the need to solder or connect wires to the unit yourself hence saving time and effort during the mounting process.

The PZ22 Piezo Switch Working Principle

The PZ22 piezo switch works like a typical piezo switch.

When you push the head, the pressure activates the piezo assembly and the energized resistor releases electrical energy that triggers the switch to actuate.

When the pressure is released, the electrical energy is dispersed and the transistor reverts to a resistive state again and stays that way until you push the PZ22 piezo switch again.

The PZ22 Piezo Switch Types

The PZ22 piezo switch differs from its size, illumination, design, color, and the material used to make them.

You can find smaller versions such as the 12mm PZ22 piezo switch or a larger size such as the 30mm version.

When it comes to illumination, you can choose between dot and ring illumination or a combination of the two.

While for colors, you can choose to have natural, black, red, blue, green, or gold and the colors can be a combination of two colors and triple colors too.

Lastly, the PZ22 piezo switch can be made up of aluminum, stainless steel, and durable plastic.

PZ22 Piezo Switch Applications

As the PZ22 piezo switch is specially designed for wet environments, it is, therefore, the best option when your application would require waterproof switches.

It can be used on the control panels of boats, yachts, or ships as well as in outdoor applications like vending machines, kiosks, and other dispensers.

The PZ22 piezo switch is also ideal for factories where controls are prone to get wet during production operations.
