Hi Limits

Shop spa hi limit switches for air button spa control systems and analog hot tub heaters. Hi limit switches are essential safety components designed to shut down the heater if water temperature exceeds safe operating limits.

These hi limits are commonly found in classic analog spa packs where mechanical thermostats and pressure switches control heater activation. Replacing a faulty hi limit switch restores safe heater operation and prevents overheating conditions in older spas.

If your hot tub is tripping, overheating, or not heating at all, a defective hi limit sensor may be the cause. Browse compatible analog hi limit replacements for dependable protection.
