Features of Presair Tinytrol Miniature Vacuum Switches
Presair Tinytrol miniature vacuum switches make electrical contact when a specific set pressure is reached. Their compact size and variety of connection styles allow for easy integration into any system. These switches provide straightforward electrical on/off control over vacuum. As vacuum rises or falls, one contact opens while the other closes, making them ideal for monitoring, controlling, and notifying. Tinytrol Miniature Vacuum Switches are preset at the factory to meet your specific requirements.
