Pressure Switch
Our pressure switch category covers a wide range of replacement pressure switches for showers, boilers and heating appliances. You will find air pressure switches, water pressure switches and differential pressure switches from brands such as Honeywell, Danfoss and Ariston. Whether you need a direct replacement for a GW50-A6 or a Ravenheat water pressure switch, we list both OEM and compatible options. Every pressure switch is checked by our technical team to confirm fitment before dispatch. In-stock orders placed by 4pm Mon–Fri (10:30am Sat) are despatched the same day. If you are unsure which switch you need, contact our Doncaster trade counter for help. We also source obsolete and refurbished parts where available.
