This silver knob is a genuine part manufactured by New World. It is made to control just your hotplate, so if the existing cooker control knob for your hotplate is faulty or has broken completely, this part is the perfect replacement for your cooker.
This silver knob may also fit certain Stoves appliances, so please check that your cooker is compatible with this part before you proceed with your order. You can do this by entering both the manufacturer and model number of your cooker on the Cooker Spare Parts homepage, which will subsequently display a list of compatible parts for your cooker.
