What it is
The ON/OFF SWITCH, part number 5142170, is a Potterton Commercial control switch used on Potterton Commercial Sirius 2 and Sirius 3 FS series boilers. It provides the manual on/off control for the appliance, allowing the boiler to be switched at the control panel. It is supplied as a standalone boiler spare.
Signs this part needs replacing
- The boiler does not respond when the switch is operated
- Power to the appliance cuts in and out when the switch is touched or held
- The switch feels loose, gritty or fails to click through its travel
- Visible damage to the switch body, lever or terminal area
Before you order
- Confirm the boiler model against the Sirius 2 or Sirius 3 FS fitment list
- Check the part number on the existing switch or the appliance documentation reads 5142170
- Isolate the electrical supply to the boiler before removing or fitting the switch
