Typically, this switch is used for burner control and is activated by a pressure threshold within the unloader where the switch is mounted. As you disengage your gun by releasing the trigger the pressure suddenly spikes within the switch. This increase in pressure will turn the burner off so that you are not constantly heating the pressurized coils with hot water pressure washers. Once the trigger is re-engaged, the pressure drops and the switch will turn the burner back on. A few other items switches may operate would include supply pumps, electric pressure washer motors, electronically controlled chemical injection systems. This 'Big' Pressure Switch has approximately 1\" x 3\" x 1\" dimensions with ratings of 250 V -15 A.\u003c\/span\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cp\u003e\u003cspan style=\"font-family: arial, sans-serif;\"\u003eBe 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.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-family: arial, sans-serif;\"\u003eO-Ring Colors indicate the following:\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan style=\"font-family: arial, sans-serif;\"\u003eYellow = 115 Activation PSI\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-family: arial, sans-serif;\"\u003eBlue = 210 Activation PSI\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-family: arial, sans-serif;\"\u003eRed = 360 Activation PSI\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-family: arial, sans-serif;\"\u003eBlack = 580 Activation PSI\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-family: arial, sans-serif;\"\u003eYou 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).\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan style=\"font-family: arial, sans-serif;\"\u003eRed = Normally Closed\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-family: arial, sans-serif;\"\u003eBrown = Normally Open\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-family: arial, sans-serif;\"\u003eBlue = Common\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Veloci","offers":[{"title":"Default Title","offer_id":49011135905985,"sku":"P-MTM-PSWITCH-1\/4IN-360PSI","price":56.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2556\/4100\/files\/DSCF7174.png?v=1744659082","url":"https:\/\/www.chem-x.com\/en-ca\/products\/mtm-hydro-1-4-big-pressure-switch-360-psi","provider":"Chem-X","version":"1.0","type":"link"}
