A clear view of Presair’s Tinytrol Miniature Pressure Switch up against top competitors V4000 & HPS-600-V. As a simple tool, we have created a competitor chart that can be found and the bottom of this post that highlights the differences between each series.

Presair pressure switches cost is comparable or lower than conventional controls to meet the needs of the original equipment manufacturer.

All switches are 100% tested with a 100,000+ cycle life.

Presair pressure switches deliver complete electrical isolation with zero voltage at the point of actuation.

Tinytrol pressure switches provide versatile and convenient sensing. Their miniature size and variety of connection styles for simple implementation into any system. These switches allow for simple electrical on/off control over pressure. As pressure rises or falls, one contact opens as the other closes. This provides a perfect solution for monitoring, controlling, and notifying.

Tinytrol Pressure Switches are designed and manufactured to exacting standards to meet the needs of original equipment manufacturers and instrument makers for a low cost, stable switch, and good repeat accuracy. The Tinytrol pressure switches are factory set from 1.5Psi to 65Psi
