Hydrotherm BM-8785 Rollout Switch 319848-301 While often categorized similarly inThe Hydrotherm BM 8785 Rollout Switch is a critical safety component engineered for high temperature thermal protection in industrial and commercial heating systems. Designed as a 350F M R rollout switch, this device monitors combustion chambers and heat exchangers for dangerous flame rollout conditions. When temperatures exceed the 350F threshold, the precision snap action mechanism interrupts the electrical circuit, requiring a manual reset to
