Tornado Tempest Microswitch Housing K50609980

The Tornado Tempest microswitch housing (part# K50609980) is the moulded carrier that holds the power microswitch (part# K66303310) on the Electronics assembly of the TV400-W26-U cordless wide-area sweeper. Tacony lists it as Microswitch Housing, Tempest. It is a small, inexpensive part doing a precise job: it fixes the switch at exactly the right distance and angle from its actuator, so that the operator control makes and breaks the circuit at the correct point of travel.

That precision is why the housing matters out of all proportion to its price. A switch is a sealed, reliable component; the plastic that positions it is the part that takes the repeated mechanical loading. When the housing cracks, distorts or loses a mounting boss, the switch moves a millimetre or two and the machine starts behaving like it has an electrical fault — when what it actually has is a switch that is no longer being pressed properly.

Compatible Models for the Microswitch Housing

Symptoms that point to the microswitch housing

• The Tempest needs the control pressed unusually hard, or held, to start.
• The machine cuts out when it is pushed over a transition or bumped.
• The switch feels loose, rattles, or can be moved by hand in its mounting.
• Visible cracking, whitening or a snapped mounting boss on the plastic carrier.
• A new microswitch has been fitted and the same intermittent starting fault remains.

That last symptom is the one worth acting on. If replacing the switch did not fix an intermittent start, the housing is very likely the real fault — the new switch is simply sitting in the same wrong position as the old one.

Fitting notes

The housing is retained with an M4 x 16 screw (part# K73032050), with a spring washer and hex nut. Remove the battery pack before working inside the control area. On refitting, check that the switch clicks crisply at the same point through the full travel of the actuator before closing the machine up — if it clicks late, or needs over-travel, the housing is not seated correctly.

Frequently Asked Questions

What does the microswitch housing do on the Tornado Tempest?

It holds the power microswitch (part# K66303310) in a fixed position and alignment relative to its actuator, so the circuit makes and breaks at the correct point in the control’s travel.

How do I know if my microswitch housing needs replacing?

Look for a switch that is loose in its mounting, visible cracks or a broken mounting boss, a machine that cuts out when bumped, or an intermittent start that survived a new microswitch. That last case is the strongest indicator — a good switch in a distorted housing still fails to make properly.

What models is the microswitch housing (part# K50609980) compatible with?

The Tornado Tempest TV400-W26-U wide-area cordless carpet sweeper. It is a Tempest-specific moulding.

Should I replace the switch and the housing together?

If the housing is damaged it is worth doing both — the switch has usually been taking abnormal loading, and both parts together cost far less than a second strip-down. If the housing is sound, the switch alone is fine.
