Air Switches, Pressure & Vacuum Switches — Safe Switching & Control Systems Since 1974!

Original equipment manufacturers worldwide use safe switching products designed and manufactured by Presair. Spas, whirlpools, jetted baths and hot tubs incorporate Presair's high quality, UL approved switches and control. Other important applications are medical equipment, plumbing and HVAC equipment and products for the home. Made in the USA. Presair takes pride in quality control and reliable operation of our components. Products are designed, manufactured, tested and shipped from Presair's facilities in Altoona, WI to clients across the globe. Every switch is individually tested before it leaves the plant.

Presair pressure, vacuum and air switches are offered in a variety of models. Our Air Switches are available to perform single or multiple functions sensing 1.5 to 3 Psi when pair with our air actuators — foot pedals or push buttons. Magictrol Sequencing Air Switch allows you to switch up to four separate pieces of equipment in sequence. Presair also offers a line of Factory Set Pressure and Vacuum switches to sense minimal pressure and pressure up to 65 Psi. If you need to sense a larger amount of pressure our Adjustable Pressure and Vacuum switches can sense up to 125 Psi and 300 inches of water. These switches are available either field adjustable or factory set allowing each micro switch to operate at a different setting. For very sensistive pressure sensing we recommend our Sensitve Differential Pressure and Vacuum Switches as these can sense anywhere as low 0.25 inches of water — comparable to a newborn baby's breath. These sensitive switches respond to rapid pulsing and handle low level switching currents. Lastly, we offer PC Board Mount Switch which are miniature single pole and double pole switches used as vacuum, pressure or differential switches where moderate accuracy is sufficient. These switches are ideal for printed circuit board mounting or a miniature switch option when paired with wire leads.
