Eureka Switch Assembly - 48...

Product details
Part 28073A is the switch assembly for the Eureka 4870 series and the related 5855-generation commercial uprights, covering the badge-shared Sanitaire models built on the same platform. It is the component that makes and breaks power at the handle every time the machine is switched on or off.
A switch on its way out rarely quits without warning. It usually announces itself first as a rocker that needs extra pressure to catch, then as flickering power under vibration, and eventually as a machine that shuts off on its own mid-pass. Those are the internal contacts wearing down from years of use, and once a switch is behaving inconsistently it tends to get worse rather than better.

Unplug the machine before starting, then transfer the wiring leads from the old switch to the new assembly one at a time so nothing gets crossed. Press each spade connector fully home before moving to the next lead, since a half-seated connector heats up under motor current and shortens the life of the new switch. Confirm your exact model number before ordering, since this platform spans a wide range of production variants.
Because this assembly serves machines built across many production years, it is worth keeping your old unit on hand until the new one is fitted and tested, so the two can be compared directly if anything about the replacement looks unfamiliar.
