Dwyer Instruments, Inc. 1638-10 Pressure Switch

The Dwyer Instruments 1638-10 Pressure Switch is a compact, electrical switching device that changes its contact state at a 10 psi pressure setpoint, delivering a precise, binary signal when the monitored pressure reaches the configured threshold in a system today. Designed specifically for AC control circuits, the 1638-10 accommodates 125 V AC, 250 V AC, and 480 V AC power, offering flexibility for different electrical environments and simplifying integration with existing panel wiring and control panels. This model belongs to Dwyer’s 1638 family of pressure switches, with the 1638-10 designation identifying its exact setpoint and electrical configuration; it provides a straightforward on/off signal suitable for interfacing with automation equipment, relays, interlock logic, or other control interfaces, depending on system design. Manufactured by Dwyer Instruments, Inc., the 1638-10 reflects the company’s focus on reliable pressure sensing and practical, easy-to-wire instrumentation for applications requiring a defined pressure trigger in diverse control installations.
