Ingersoll Rand 23474570 Pressure Switch for Two-Stage Compressors | 135 PSI Cut-In / 175 PSI Cut-Out

Overview

The Ingersoll Rand 23474570 pressure switch is a robust control component designed to support two‑stage air compressor systems. Engineered for reliability in busy workshops, it pairs with a broad range of Ingersoll Rand models and select single‑phase configurations, offering precise pressure management without complicating maintenance.

Compatibility and range

This switch is built to operate with most three‑phase Ingersoll Rand reciprocating compressors, including popular models such as 2340, 2475, 2545, and 7100. It also accommodates certain 5–7.5 HP single‑phase 2475 configurations. This broad compatibility can simplify replacements and future upgrades within established systems.

• 135 psi cut‑in for responsive start and pressurization
• 175 psi cut‑out to maintain a consistent pressure ceiling
• Includes an unloader valve to assist smooth restarts
• NEMA Type 1 enclosure provides standard protection for typical shop environments
• Does not include a built‑in shut‑off switch

Installation notes

For a proper seal during installation, apply Teflon tape to threaded connections. Review the recommended installation video or contact our Air Tech team at 800-247-7378 for guidance. Following these steps can support a reliable connection and long‑term performance.

• Prepare threads with Teflon tape prior to mounting
• Verify alignment and electrical connections per model requirements
• Consult the video or Air Tech support if you have questions during installation

Real‑world use and expectations

In typical shop or light manufacturing settings, this switch can help maintain stable pressure within a two‑stage system, potentially reducing cycling and wear on downstream components. The enclosed design offers protection in dusty or humid environments, and the unloader valve supports smoother restarts after shutdown.

Note that outcomes depend on the overall system configuration and other components. View this switch as a configurable piece that supports your compressor’s pressure control goals, rather than a guaranteed result. If upgrading from an older unit, confirm compatibility with your current models and power rating to ensure a seamless fit.

Choosing a switch designed for a broad Ingersoll Rand lineup can provide a familiar interface and straightforward replacement path, with installation guidance and support available if needed.
