Key Features

- Direct Drop-In Replacement — Matches the original connector configuration and mounting position of the factory-installed switch for a straightforward swap.
- Confirmed D640B Fitment — Verified for use on D640B equipment, so you can order with confidence knowing this is the correct part for your machine.
- Restores Reliable Start Function — A faulty starter switch can prevent the machine from cranking or cause intermittent start failures; this genuine replacement restores full ignition control.
- Genuine Multiquip OEM Quality — Manufactured to Multiquip's original design tolerances, ensuring the switch engages and releases cleanly under repeated use without premature contact wear.
The starter switch is the operator-activated control that completes the electrical circuit between the battery and the starter motor, initiating engine cranking when engaged. When a starter switch wears out or fails internally, the machine may not respond to the ignition input at all, or it may crank erratically, making it impossible to start the engine consistently. Replacing a faulty switch promptly with a correct OEM part restores dependable start-up performance and prevents unnecessary strain on connected electrical components.
