Tinytrol® Miniature Vacuum Switches

Tinytrol® vacuum switches provide compact, low-profile vacuum sensing with a variety of connection styles for easy integration into system designs. These switches offer straightforward electrical on/off control based on system vacuum. As vacuum rises or falls, one contact opens while the other closes. This provides a perfect solution for monitoring, controlling, and notifying.

Tinytrol® Vacuum Switches are factory set to actuate at vacuum levels ranging from 2.50 to 300 inches of water. They are available with multiple air connection types, mounting options, and electrical ratings to support a wide range of applications.

Each switch is designed and manufactured to precise standards to meet the performance, cost, and repeatability requirements of original equipment manufacturers and instrument builders.

Tinytrol® vacuum switches are more economical as they are comparable or lower than conventional controls meeting the needs of original equipment manufacturers worldwide. All switches at 100% tested with a +100,000 cycle life.
