LEFOO Pressure Switch LF10-W1 1/4NPT Adjustable 30-50 PSI Industrial

Description

Product Overview

The LEFOO LF10-W1 pressure switch is engineered for demanding industrial environments. It delivers a selectable pressure range of 30‑50 psi, allowing users to set cut‑in at 30 psi and cut‑out at 50 psi, with optional adjustments to 40‑60 psi or 60‑80 psi for versatile applications. Constructed with a compact 3.7 × 3 × 2.6 in housing and weighing only 10.4 oz, the unit features a 1/4 NPT female port for straightforward integration. Its electrical rating of 120 VAC 20 A / 240 VAC ensures compatibility with a wide range of control panels. The normal‑close (NC) contact arrangement provides reliable circuit continuity, and the design eliminates drift in pressure settings, guaranteeing consistent performance over time.

Usage

Designed for HVAC systems, air compressors, water pumps and other process equipment, this switch excels in environments where precise pressure regulation is critical. Install it in control panels, machinery enclosures or outdoor units where space is limited. Its robust construction tolerates temperature fluctuations and vibration, making it suitable for factories, workshops and commercial facilities.
