Rheem-Ruud 47-20045-02 Limit Switch The switch is designed toThe Rheem Ruud 47 20045 02 Limit Switch is a critical safety component designed for high voltage HVAC systems. As a furnace high limit switch, this DPST normally closed switch is engineered to break the electrical circuit if internal plenum temperatures exceed safe operating parameters. This specific model features a 150F fixed open temperature and a 110F fixed close temperature, facilitating an auto reset function once the system cools to a safe
