Pressure switches are prone to malfunctions. Although most switches and its parts are rough and is a solid-state devices, these have a limited lifespan and is vulnerable to damage from different causes. This has been evident so the necessary maintenance should be done on a periodic time manner.

Here’s the common malfunction causes of pressure switches:
- Chemical Damage – The solution is to avoid exposing the pressure switch and its materials to incompatible chemical and solutions.
- Electrical Interference – Electrical tests can be done which includes overvoltage resistance and load dump.
- Water – Ensure to avoid the water getting into the device, however, incidental contact is most likely inevitable in most of the applications.
- Temperature – Most electronic device functions at a specified ranges of temperature. The use of above or below temperature with reference to the standard may lead to a failure.
- Pressure – Similar to temperature, a switch is designed to function at a standard pressure set, working beyond or below the standard failure may cause a breakdown.
