Snowbeast428 - First of all, let me say of all the aftermarket hoses available, the one Cheesewonton linked to would be your best choice. However, I would NOT buy it, and here's why - they have too many problems!
With the aftermarket hoses, the first thing to give trouble is the sliding suction relief valve on the top of the hose. They loosen up within a year of ownership, and you usually wind up having to hold it closed with a rubber band or a piece of tape. The screw holes in the plastic will also within a year or 2 start to not hold the screws that hold the handle trim in place. Also, it is likely within a few years the receptacle that mates to the plug in the sheath will get scorch marks or burn out, meaning the hose will no longer transmit energy to the wand to power the powerhead unless you replace the entire handle assembly. The reason for this is the notches in the metal stub tube are deeper on the aftermarket hoses than the genuine Electrolux hoses. The metal clip on the sheath won't "grip" those notches on the aftermarket hoses as effectively, causing play and wiggle room as you push and pull the wand and powerhead. If you try the aftermarket Electrolux wand and sheath, you will actually notice the metal clip is stronger on the aftermarket versus the genuine - this is intentional, so that it grips the metal notches on the aftermarket hose it's intended to be used with better.
If you want the ability to shut off your powerhead, I would suggest you should replace your powehead with a PN6 or later from the late 80's/early 90's that has the sliding power switch on the powerhead, and get a nice genuine used Electrolux hose. That way you avoid any problems with your new hose breaking or failing prematurely. If you do go with the aftermarket option Cheesewonton linked to, I would also insist on replacing the entire wand assembly with one from the Perfect C103 / Clean Obsessed canister.
Below is a link to a nice used genuine Electrolux hose. Good luck.
