The Multiquip 1628663602 Starter Switch is a genuine OEM component designed for DLW300ES series diesel light welders and DA7000SSA2GH, DA7000SSA2, DAC7000SSA, DAC7000SSW, and DAC7000SS series diesel-powered generators and super-silent alternators. As a direct OEM replacement, it meets the original design and electrical specifications set by Multiquip, ensuring consistent, dependable operation every time the engine is engaged. Sourced directly through authorized channels, this part is the correct choice when restoring your machine to factory-operating condition. Confirm your model code before ordering to ensure a correct match.
Key Features
- OEM Electrical Specification Match — Built to the original switching specification, ensuring correct ignition circuit engagement and consistent start signal delivery without voltage drop or contact failure.
- Direct Drop-In Installation — Engineered to the same connector and mounting configuration as the original, allowing straightforward swap-out without wiring modifications or bracket adapters.
- Broad Fitment Across Welder and Generator Lines — Compatible with DLW300ES series diesel light welders and DA7000SSA2GH, DA7000SSA2, DAC7000SSA, DAC7000SSW, and DAC7000SS super-silent generator models.
- Protects the Starting Circuit — A worn or faulty starter switch can cause no-start conditions, intermittent cranking, or unintended engagement of the starter motor — replacing it restores clean, predictable ignition behavior.
- Electrical Safety Assurance — On diesel welders and generator sets, a compromised starter switch can create unsafe start conditions or starter motor damage; using the correct OEM part maintains proper circuit isolation and operator control.
The starter switch is the operator-activated control that completes the ignition circuit and sends the signal to engage the starter motor, bringing the engine to life. On diesel-powered equipment such as welders and generator sets, this switch must reliably close and open the circuit under load — a degraded switch can cause hard-start or no-start conditions, intermittent cranking, or in some cases continuous starter engagement that can damage the motor. Replacing a faulty starter switch with the correct OEM part restores full operator control over the engine starting sequence and protects downstream electrical components from irregular current draw.
