Overview

The Miller 206746 Pressure Switch is a purpose-built component designed for industrial pressure monitoring applications. Operating as a normally closed (NC) switch with a fixed 20PSI activation point, it provides a reliable and repeatable trigger for systems that need to detect when pressure reaches a specific threshold. The normally closed configuration means the electrical circuit remains complete under standard conditions and opens once the pressure hits 20PSI, making it well suited for safety shutoffs and alert systems where a fail-safe default state is preferred.

As a genuine Miller replacement part, the 206746 is intended to drop directly into equipment and systems that originally specified this component. This eliminates guesswork around compatibility and ensures the switch meets the same performance standards as the original factory-installed unit. While the fixed setpoint limits its versatility for variable-pressure applications, it offers simplicity and consistency for installations where 20PSI is the target operating pressure.
