PSE Metallic Switch

The PSE metallic switch from SCHURTER is a series of piezo-electric switches known for their extremely long lifetime and seal-tight surface, which protects against dust and fluids. In addition to these already proven features, the operating temperature extends from -40°C up to +85°C for the normally open (NO) types. The switches can now be used in outside applications where extreme temperatures and temperature fluctuations may occur.

Piezo-switches contain no moving parts, have a sturdy metal housing made of anodized aluminum or stainless steel, and are hermetically sealed. Virtually no material wear or mechanical fatigue occurs, resulting in a rated lifetime of greater than 20 million switching cycles – practically unlimited. The piezo-switches are resistant to dirt, sand, dust, and water. Additionally, they will not freeze or stick after exposure to fluids. They are especially suited for applications located in areas exposed to heavy snow and ice, including ticketing and toll machines, call boxes, building access controls, construction equipment, and transport vehicles.
