Dwyer Pressure Switches

Models: 1638-0, 1638-1, 1638-2, 1638-5, 1638-10

Product Overview

The Dwyer Pressure Switches (Series 1638) are reliable, precision instruments designed for pressure-based control in HVAC and industrial processes. These switches feature visible set-point indicators and large diaphragm designs for accurate operation in low-pressure ranges, enabling precise control of pumps, fans, and valves.

Capable of handling current loads up to 15 amps, they directly support small electrical loads without additional relays, simplifying system design and reducing installation costs.

Key Features

Visible Set-Point Indicator

Front-facing indicator allows quick visual confirmation of pressure set points, simplifying on-site adjustments and troubleshooting without specialized tools.
Large Diaphragm Design

Enhances sensitivity and accuracy in low-pressure applications, enabling precise pressure threshold detection for reliable system control.
High Current Load Capacity

Supports up to 15 amps, suitable for direct connection to small motors, solenoids, and alarms, eliminating the need for intermediate relays.
Versatile Pressure Ranges

Multiple models cover different pressure spans from 0-1 psi to 0-10 psi to suit various application requirements.
Rugged Construction

Durable housing suitable for indoor HVAC and general industrial environments with reliable performance in typical operating conditions.
