Features of Presair Tinytrol Factory Set Pressure SwitchesFactory Set Pressure Switch Cross-Reference

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