HVAC Safety Interlock Switch | 16A 250VAC | UL Recognized | Panel & Access Door Safety Switch

HVAC Safety Interlock Switch
The ASI HVAC Safety Interlock Switch is designed to automatically disconnect electrical power when an HVAC access panel, filter door, or service panel is opened. Rated for 16A at 250VAC and UL Recognized, this safety interlock switch helps protect maintenance personnel by preventing equipment operation while service access panels are open.

Commonly installed on air handling units, rooftop HVAC equipment, ventilation systems, and commercial HVAC cabinets, the switch provides a simple, reliable method of interrupting power during maintenance, inspection, and filter replacement.

Why Install an HVAC Safety Interlock Switch?
HVAC equipment contains energized electrical components, high-speed blower fans, belts, and moving mechanical assemblies that can present hazards during maintenance.

An HVAC safety interlock switch automatically disconnects power whenever an access panel is opened, helping reduce the risk of injury and preventing equipment from operating while technicians are servicing the unit.

What Problem Does This Solve?
Maintenance personnel frequently need to open HVAC equipment to:
• Replace filters
• Inspect blower assemblies
• Service electrical components
• Troubleshoot control systems
• Perform routine maintenance

Without an interlock switch, equipment may continue operating with the access panel removed, exposing personnel to moving components and energized electrical circuits.

The HVAC Safety Interlock Switch automatically interrupts power whenever the access panel is opened, helping improve technician safety while protecting equipment.
