<< Back To FAQ's Why does the Thermophore Classic™ have a special, spring-loaded switch?   The Thermophore® pack treatment is so soothing and relaxing that users often doze off as their pain and tension eases. If the user does fall asleep while using the original Thermophore® Automatic Moist Heat Pack™, their hand will relax, automatically turning the unit off. No other product has a safety switch quite like the Thermophore® Automatic Moist Heat Pack™. Our Thermophore® Arthritis Pad™ offers the quality and intense heat users have come to expect, plus the added convenience of a pre-set control to leave your hands free. Users turn the heat on and off with simple push-buttons to control the level of heat to their personal preference. If they happen to doze off or become distracted during treatment, the unit automatically shuts off at the end of the current 20-minute cycle.   View all Thermophore FAQs & Answers
