Red On Off Rocker Switch for Numatic Henry Vacuum Cleaner 20A

Red On Off Rocker Switch for Numatic Henry Vacuum Cleaner 20A

If your Henry vacuum will not switch on, cuts out when you touch the switch, or the red rocker has cracked or gone loose, a worn on/off switch is a common cause. This OhSo.Shop Essentials red rocker switch is a 20 amp replacement for the main power switch on Numatic Henry cylinder vacuums and many other Numatic models, including Hetty, James and commercial NRV and NVQ machines. It is a simple, low-cost way to get a hard-working vacuum running again.

What This Part Does

The rocker switch on top of the machine is the main power switch. It connects the mains supply to the motor when switched on and cuts it when switched off. Because it is pressed every time the vacuum is used, often with a foot on busy commercial machines, the rocker can crack and the internal contacts can wear, leaving the vacuum dead or cutting in and out.

Common Fault Symptoms

• Your vacuum does not start when the switch is pressed, even though the plug, fuse and cable are fine.
• The vacuum cuts in and out when the switch is touched or the machine is moved.
• The red rocker is cracked, loose or pushed in.
• The switch feels hot, crackles or smells of burning (stop using the vacuum).

Repair Difficulty

Easy to moderate: the motor head is lifted off the tub and the top cover opened to reach the back of the switch. The wires are moved across from the old switch one at a time, and the new switch clips into the same opening. Take a photo of the wiring before you start.

Typical Tools Required

• Screwdriver set
• Small flat-blade screwdriver to release the switch clips

Description

This is a compatible OhSo.Shop Essentials replacement part, equivalent to Numatic 220552. It is not made by Numatic. Check your existing switch before ordering: this is the single on/off rocker, not the Hi/Low two-speed switch.

Before replacing the switch, check the plug fuse and the mains cable, as a damaged cable gives the same symptoms. Your model name is printed on the machine and on the rating label. If you are unsure whether this switch fits, send us your model details and we will check for you.
