Microswitch – K66303310Find genuine Tornado Tempest electronics replacement parts for Model TV400-W26-U. This sheet covers the system control board (part# K46833200) and motor control board (part# K46833210), the power microswitch (part# K66303310) and its housing (part# K50609980), and the fasteners that hold the assembly together. The two boards do different jobs: the system board powers the machine up and reads the controls, while the motor board drives the brushroll, blower and side broom — which is why a dead machine and a machine that runs but will not drive a motor point at different parts.

Frequently Asked Questions
What battery and charger does the Tornado Tempest use?
The Tempest TV400-W26-U runs on the 36V 7.5Ah lithium-ion pack, part# K24450750, charged by the 36V quick-charger, part# K24450530. Both are shared with the Tornado Strike TV190-W10-U, and the battery is also used on the Zephyr TV570-Q03-U — so if you run more than one Tornado cordless machine, the packs interchange.
My Tempest is completely dead — is it the battery or the electronics?
Start with the cheapest checks. A pack that will not hold charge is the most common cause, but a machine that stays dead on a known-good charged pack usually points at the power microswitch (part# K66303310) or the system control board (part# K46833200). A machine that powers up and responds but will not drive a motor points instead at the motor control board (part# K46833210).
Why do callouts 30 and 80 have no part number?
Those two positions on the factory Electronics sheet are not catalogued by Tornado as individually orderable items. We have left the rows on the table rather than hiding them, so the numbering matches the diagram you are looking at. Call us at 763-535-0770 with your machine in front of you and we will work out what you need.
There are two spring washers listed — which one do I need?
Tornado publishes no dimensions for either, so they are identified here by the fastener group they belong to on the factory sheet. Part# K73130170 is the one fitted with the M4 hex nuts (five on the machine); part# K73130160 is fitted with the single M5 hex nut. If you are unsure, call 763-535-0770 with your part number and we will confirm it.
Can I ship a Tempest battery?
Lithium-ion packs of this size are regulated for transport and cannot go by air. Call us at 763-535-0770 before ordering and we will confirm the shipping options to your address.
