BINARY TYPE SAFETY SWITCH

A safety switch simply works by opening and closing circuits.
As long as pressure in the high side line (the line between the condenser and 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.

TRINARY TYPE SAFETY SWITCH

Where 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 switch can be mounted,
anywhere in the high pressure line between the condenser and the evaporator.
Mounting the safety switch behind the dash near the evaporator hides the switch out
of view for a clean underhood appearance.
