Additional information

This snowblower ignition switch, part number 925-04031B, mounts in the control panel and connects to the wiring harness so turning the key sends power to the starter circuit and engine electrical system. It provides a simple interface to start the engine and shut it off when the job is done.

If the ignition switch wears, becomes intermittent, or fails, you may notice the engine not starting, flickering electrical response at the key, or loss of power to accessories. A worn contact inside the switch can cause inconsistent engagement or require jiggling the key to get a response.

Disconnect the battery and spark plug wire before starting the repair to prevent accidental startup. Electrical components and terminals can have sharp edges, so wearing work gloves can help protect your hands during installation. Make sure the switch is secured firmly and the wiring is reconnected correctly before using the snowblower.
