Langir PP22 Piezo Switch Introduction
The Langir PP22 piezo switch is a type of piezo switch made from durable plastic with an illumination feature.
Depending on its type it illuminates when you press it or after pressing it, it stays illuminated until you press it again where the illumination turns off.
It is made from white plastic with exceptional durability and reliability.

PP22 Piezo Switch Features
The PP22 piezo switch has plenty of great features that your application can take advantage of.
First, it has illumination and if it’s a momentary action switch, it illuminates while it is being pressed which makes it a great indicator that the switch is activating the function it was installed for.
Since it can be IP68 or IP69K sealed, this means that it is highly dust and water proof which makes it ideal for outdoor applications, wet environments, and even for tough environments.
The PP22 piezo switch is also easy to operate, as you only need to apply an almost negligent force to actuate it.
It is also designed to be compact using a piezo assembly module without any mechanical parts which make it void of wear and tear thus prolonging its lifespan.
The PP22 piezo switch also has wire termination which means you don’t have to connect wires to it anymore, therefore cutting down the mounting time for faster installation.
Working Principle of the PP22 Piezo Switch
The PP22 piezo switch works similarly to its metal piezo counterparts.
It has a piezo assembly module composed of self generating piezoelectric elements that when you press the PP22 piezo switch’s head, a charge polarization phenomenon happens inside the module.
This phenomenon triggers the switch to actuate and stops when the pressure is lifted until it the head is pressed again.
The PP22 Piezo Switch Types
The PP22 piezo switch has different types based on its size, illumination colors, and waterproof properties.
You can find types that are ideal for space limited applications such as the 12mm PP22 piezo switch but there is also a bigger size such as a 30mm PP22 piezo switch.
The illumination colors can be blue, green, red, or a combination of red and green, red and blue, or green and blue.
You can also choose red, green, and blue continued LED colors.
Finally, you can find sealed IP68 and IP69K PP22 switch great for environments prone to water ingress.
Applications of the PP22 Piezo Switch
The PP22 piezo switch has many applications which can be any of the following but not limited to:
- Automatic gas pumps
- Automotive control panels
- Restaurants or bakeries
- Car wash systems
- Control panels
- Cosmetics manufacturing
- Dairy factories
- Food preparation and packing
- Gate control access and security doors
- Medical and pharmaceutical equipment
