Tornado Tempest Contact Display K66340200

The Tornado Tempest contact display (part# K66340200) is the indicator mounted in the battery housing of the TV400-W26-U cordless sweeper. Tacony lists it as Contact Display; the Tacony parts book calls the same number a Brush Pressure Display. We use the dealer name, and flag the disagreement rather than quietly choosing the one that reads better.

Either way, its function is to tell the operator what the machine is doing at the point where the brush meets the floor. On a cordless sweeper that feedback is more useful than it is on a corded machine: brush pressure directly trades pickup against runtime, and without an indication the operator has no way to see that the brush is loaded harder than it needs to be until the battery runs down early.

Compatible Models for the Contact Display

• Tornado Tempest Wide-Area Cordless Carpet Vacuum Sweeper — Model TV400-W26-U

Symptoms that point to the contact display

• The display is blank or dead with the machine powered up.
• It reads full scale or zero regardless of the adjustment setting.
• Segments or indicators are missing or stuck.
• The lens is cracked, crazed or water-marked so it cannot be read.
• The reading does not change when the height adjustment knob is turned.

Before ordering, confirm the adjustment train itself is working — if the knob (part# K53224590), lever (part# K51297940) or twisting bolt (part# K51053320) is not actually moving the brush, a perfectly good display will correctly show no change.

Fitting notes

Remove the battery pack first. The display sits in the battery mount (part# K50321850) next to the on/off switch (part# K66304680). Note the lead routing and connector orientation before disconnecting. Once fitted, run the height adjustment from one end of its range to the other and confirm the display tracks it before closing the housing.

Frequently Asked Questions

What does the contact display do on the Tornado Tempest?

It shows the operator the brush pressure and contact status at the floor, so the brush can be set for effective pickup without being loaded harder than necessary and shortening runtime.

How do I know if my contact display needs replacing?

If it is blank, stuck at one reading, missing segments, or does not respond when the height adjustment is turned. First confirm the adjustment train is actually moving the brush — a good display correctly shows no change if nothing is moving.

What models is the contact display (part# K66340200) compatible with?

The Tornado Tempest TV400-W26-U wide-area cordless carpet sweeper. PartSmart lists it against the Tempest alone.

Tacony and the parts book give this part two names — which is right?

Both refer to part# K66340200. The dealer catalogue calls it a Contact Display and the parts book a Brush Pressure Display. We list it under the dealer name and note the difference so you can match it either way.
