Ashcroft C120B Snap Action Switch

The Ashcroft C120B Snap Action Switch is a compact, fast-acting electrical switch designed for integration into pressure-sensing equipment, delivering a crisp, decisive contact change. It actuates at 30 psi and is rated for up to 15 A at 125 VAC or 250 VAC, enabling robust performance for AC-powered circuits used in industrial instrumentation. The snap-action design minimizes contact chatter and bounce, helping ensure clean transitions for downstream controllers and annunciators even in demanding environments, while the 30 psi actuation point provides a clearly defined threshold for monitoring systems. Designed for use with Ashcroft pressure-sensing equipment and related instrumentation, the C120B offers a precise, purpose-built solution when a specific pressure threshold and AC current capability are required.
