MTM Hydro 3/8" Big Pressure Switch - 360 PSI
Be sure to review the specification requirements before purchasing any type of switch as O-ring colors indicate activation PSI specific to your machine. The 'Wet' portion of the switch measures a fraction of an inch and therefore requires a lower PSI for activation as you will notice below.
O-Ring Colors indicate the following:
- Yellow = 115 Activation PSI
- Blue = 210 Activation PSI
- Red = 360 Activation PSI
- Black = 580 Activation PSI
You can install this switch in the 'Normally Closed' or 'Normally Open' position depending upon assembly instructions on your pressure washer by connecting two of the three leads (see image).
- Red = Normally Closed
- Brown = Normally Open
- Blue = Common
