This switch assembly performs two distinct func-
tions. The first function prevents the compressor
from operating if system charge is lost or ambient
temperature is too low. The second stops compres-
sor if head pressure increases to unsafe levels. It
automatically resets when pressure drops back to
normal. Install Binary
