PRESSURE SWITCHES

What does a pressure switch do?

A pressure switch is a device that monitors the pressure level in a system and activates or deactivates the electrical circuit based on whether the pressure is above or below a preset limit. In the context of air systems, like those offered by HornBlasters, a pressure switch is used to control the air compressor automatically. It ensures the compressor kicks on to refill the tank when the pressure drops too low and turns it off when the tank reaches the desired pressure level to prevent overfilling and potential damage.

How can you tell if a pressure switch is bad?

Signs that a pressure switch may be failing include the air compressor not turning on or off at the correct pressures, the switch not engaging or disengaging smoothly, or erratic behaviors such as frequent on/off cycling. To diagnose issues with a HornBlasters pressure switch, you can use a multimeter to check for continuity in the switch circuit when it is activated. If the switch does not close (or open, depending on design) at the set pressure points, it may need to be replaced.

Is a pressure switch the same as a flow switch?

No, a pressure switch and a flow switch are not the same. A pressure switch measures the pressure level within a system and operates based on changes in pressure. In contrast, a flow switch activates based on the flow rate of a fluid through a system. They serve different functions: pressure switches are crucial for managing the operation of pumps and compressors, as seen in HornBlasters' air systems, while flow switches are often used to monitor and ensure proper fluid flow in applications like plumbing or HVAC systems.
