Pressure Switches - MCI A/C System

On the air conditioning system of MCI coaches, there are a number of pressure switches used to control the A/C compressor and to prevent damage to the system. The main differences between these switches are the pressure settings and whether the switch contacts are normally open or normally closed.

Below is a list of pressure switches used by MCI with different characteristics listed (wire color, pressure ratings, etc.) All the part numbers listed are stocked by MCI Service Parts.
