INTERLOCK SWITCH | IHXILS1930

The Hayward Interlock Switch (IHXILS1930) is a safety mechanism in Hayward pool heaters that prevents unsafe operation by ensuring critical components are properly engaged before allowing ignition.

• Monitors Safety Conditions:
• The interlock switch ensures that conditions (such as proper venting, water flow, or closed access panels) are met before allowing the heater to start.
• Prevents Unsafe Operation:
• If the switch detects an issue—like an open panel, improper airflow, or another safety concern—it interrupts the ignition sequence, preventing the heater from turning on.
• Works with Other Safety Features:
• These are often used alongside pressure switches, vent safety switches, and limit switches to ensure the heater operates safely.
