I need to replace a boost pump switch as it is malfunctioning. The pump continues to run even when switched off. I have a fairly standard set up with a row of 7 or 8 toggle switches on the lower left side of the panel. The boost pump is the fourth switch in from the left. Is it possible to remove just the bad switch, or should I prepare to remove the whole row of switches? I had the panel done by a shop including the switches, so I'm not entirely familiar with the installation. It looks like the row of switches are all connected to a bus, so I will probably need to remove the whole thing to get that one switch out.
