Frequently Asked Questions

YOUR QUESTIONS, ANSWERED.

Are the Tinytrol Pressure Switches adjustable?

No. All Tinytrol Pressure Switches are factory set between 0.25 to 65 PSI. You can view our adjustable pressure switches here.

My application will expose the switch to hazardous chemicals and/or gases. How will this affect the switch’s performance?

We offer a variety of diaphragm material options to meet different application needs. 

Here’s a guide to the different options available.

My application has a small or large amount of current. What are the pressure switch ratings?

We offer a variety of micro switch options to meet application requirements up to 25 Amps @ 240VAC. Learn more   here!

What do you mean by PSI rising / falling?

Pressure switches are measured by inches of water, or PSI. Once the switch rises or falls the contacts will open and close based on the hysteresis, or deadband.

Read a more  detailed explanation here.

What’s the difference between a pressure and vacuum switch?

Pressure switches push against the diaphragm & plunger inside the switch versus a vacuum switch pulls the diaphragm away from the plunger inside the switch. Another way to think of vacuum switches is a negative pressure switch.  Here’s an illustration to help!
