The electro-magnetic clutch disengages the compressor from the belt when compressor operation is unnecessary, or unwanted. The clutch is engaged or disengaged both by the control panel on the dash by the actual demands of the system. In some systems, the clutch constantly "cycles" compressor operation on and off. In others, the compressor runs continuously as long as the system is turned "on".
