Overview

The CCS 604VM1 Pressure Switch is part of the CCS 604 series, widely used in industrial automation, aerospace, and process control. It is a SPDT (Single‑Pole Double‑Throw) switch offering adjustable setpoints for vacuum and low‑pressure applications.

Built with CCS’s Dual‑Snap® disc spring principle, the switch ensures stable, repeatable performance, even under vibration and shock. Its rugged construction makes it suitable for field or panel installation.

Technical Specifications
