Tornado EB 30/1 Switch K66304130

The switch (part# K66304130) is the electrical switch that sits beneath the yellow on/off pushbutton on the Tornado EB 30/1 electric broom. The button is what the operator touches; this is the component that actually makes and breaks the circuit to the control board, and from there to the brush motor.

Diagnosing a failed switch

A failed switch has a distinctive signature: the button still feels right — it depresses and springs back cleanly — but the machine does nothing, or it starts only when the button is pressed at a particular angle or with extra force. Intermittent running that corresponds to pressure on the button, rather than to movement of the machine, is the same fault. If the broom cuts out when the button is nudged in normal handling, the switch contacts are on their way out.

Test for continuity across the switch with the button pressed. No continuity, or continuity that comes and goes as the button is worked, confirms it. If the switch passes that test and the battery and charger are both good, the next item to look at is the complete electronics board (part# K46820920).

Order of investigation

On a machine that will not start, work from cheapest to dearest: battery charge, then charger output, then this switch, then the pushbutton (part# K43240470) if the action feels wrong, then the control board. Most no-start faults are resolved before the board.

Frequently Asked Questions

What does the switch do on the Tornado EB 30/1?

It is the electrical switch under the yellow on/off pushbutton. The button is what the operator touches; the switch makes and breaks the circuit to the control board and from there to the brush motor.

How do I know if the switch has failed?

The button still feels right — clean action, springs back — but the machine does nothing, or starts only at a particular angle or with extra pressure. Intermittent running that tracks pressure on the button rather than movement of the machine is the same fault. Test for continuity with the button pressed.

What order should I check things in on a no-start fault?

Cheapest first: battery charge, charger output, this switch, then the pushbutton (part# K43240470) if its action feels wrong, then the complete electronics board (part# K46820920). Most no-start faults are solved before the board.

What models is the switch (part# K66304130) compatible with?

The Tornado EB 30/1 Electric Broom, Models 93220 and 93222.
