W E Anderson Dual Action
Explosion Proof Pressure Switches

Accurate, dependable long lived operation results from the built-in quality Duotect pressure switches. they are designed for sequencing work, where two different actions are to be triggered, as pressure of a liquid or gas increases or decreases. This permits control and protection of many types of equipment and systems subject to pressure variations.

The switches may be adjusted to operate together, or at opposite ends of the range, or at any two intermediate setpoints. They can be easily field adjusted. For quick maintenance, the threaded top is removed to adjust or service switches without disturbing electrical or pressure connections.
