Numatic Contact Kit - Henry Dry Vacuum

A spring contact kit for Numatic's Henry canister vacuum, part 220988. Contact kits like this replace the small spring-loaded electrical contacts inside the machine, the points where power has to make a physical connection rather than run through a fixed wire joint. Dealer part indexes list the same number for the Hetty as well as the Henry.

Spring contacts wear or corrode with use the way any repeatedly-made electrical connection does, and the failure they cause is usually intermittent rather than a clean dead machine. Power that cuts in and out as the machine is moved, a motor that needs a wiggle of the cord or a knock on the body to start, or a machine that runs fine one day and not the next, are all worth checking the contacts for before assuming the motor or switch has failed outright. Discoloration or a dull, pitted look on the contact face is usually visible once the housing is open, and is a fairly reliable sign the kit needs replacing rather than just cleaning.

Confirm this kit against the contacts in your own machine before ordering. Numatic has produced the Henry line across many years and variants, and a submodel-specific match is worth checking against the rating plate rather than assuming every Henry uses an identical set. Unplug the machine and let it sit before opening the housing.
