Hot Rod Air safety switches work by opening and closing your A/C compressor circuits. As long as pressure in the high side line (the line between the condenser and the evaporator) is within safe operating levels, the safety switch will keep the electrical circuit between the thermostat and the compressor closed. However, when pressures either rise above or fall below safe levels, the switch opens the circuit to shut down the system. While a binary switch will simply shut down the compressor, the trinary switch has an added feature. When pressures start to rise, the trinary switch will engage an electric fan to bring additional air across the condenser to lower high-side pressure. Both the trinary and binary safety switches can be mounted anywhere in the high-pressure line between the condenser and the evaporator. Mounting the safety switches behind the dash and near the evaporator keeps them out of sight for a clean underhood appearance.
