What do you need to know about air flow switches?

Air flow switches are widely found in all manner of ducting and HVAC systems, often using a (mechanical) paddle-type operation to trigger a microswitch when flow increases or decreases beyond a set rate or volume.

What do you need to know about paddle flow switches?

Paddle flow switches are a type of mechanical switch that’s activated directly by pressure from the medium – usually liquid – passing through the duct or channel into which the switch is inserted. The paddle is often a small strip of metal or plastic that hangs inside the pipe and is attached to either a tensioned spring or a series of magnets.

What can a flow switch do if the rate drops?

If the rate exceeds or drops below what’s required, it can instantly trigger a series of actions such as activating an alarm, powering on a pump, diverting flow, shutting off parts of the system. Which actions a switch performs will depend entirely on the type of switch and what it’s been designed for.

What does a flow switch on a shower head do?

A shower pump flow switch helps maintain water pressure being sent up through the piping and out of the shower head. They can be found on both hot and cold supply channels, and are generally mechanical. Demand for water to the shower head causes the switch to activate and this, in turn, completes a circuit which tells the pump to begin operating.

A louvered damper enables control of the air, which can be directed in at least one direction or, in some cases, up to as many as four, or diffused altogether. These are usually the best floor registers for air flow in residential spaces.
