Standard Motor Products ignition starter switch US130T — direct-fit vehicle-specific replacement, precision contacts

The Standard Motor Products US130T is a vehicle-specific ignition starter switch engineered to restore reliable engine starting and maintain factory fit and function.

When the key turns but the engine won't crank, the ignition starter switch is often the first electrical component to check. The US130T from Standard Motor Products is designed as a direct-replacement unit that installs in the original mounting location and meets the manufacturer’s fit specifications. Built in the United States and packaged to protect the part during shipping, this switch is intended for technicians and DIYers who need a dependable, vehicle-specific starter switch without altering wiring or dash components.

How does the US130T improve starting reliability?

The starter switch completes the circuit between the ignition key and the starter motor. A properly functioning switch ensures consistent electrical contact, reducing intermittent no-starts and preventing starter solenoid wear from erratic engagement. Choosing a direct-fit unit like the US130T helps avoid modification and simplifies troubleshooting.

• Direct-replacement design for factory fit
• Precision contacts reduce electrical resistance
• Meant to maintain original starting circuit behavior

What should I know about installation and vehicle compatibility?

The US130T is vehicle-specific, so confirm fitment against your vehicle’s year, make, model, and original part number before purchasing. Because it is manufactured to match OE mounting points and connector styles, installation typically involves removing trim, unplugging the old switch, and securing the new unit in place. For some vehicles, basic hand tools and dash removal are required.

• Fit type: Vehicle Specific — check compatibility first
• Connector and mounting match original equipment for easier swap
• Professional installation recommended if dash disassembly is unfamiliar

What are the product specifications and packaging details?

The US130T comes packaged to protect the part and includes country-of-origin labeling to help with sourcing and warranty records. Standard Motor Products provides packaging dimensions useful for storage and inventory management. These physical details also help verify you received the correct boxed unit when ordering online or by parts catalog.

• Country of origin: United States
• Package dimensions: length 4.133 in, width 6.05 in, height 4.567 in
• Boxed for shipping and parts-room storage

How do I diagnose whether the starter switch is the issue?

Typical symptoms of a failing ignition starter switch include no-crank condition with accessory power, intermittent starting, or the starter engaging only in certain key positions. Before replacing the switch, verify battery charge and starter/solenoid operation; many starters can be bench-tested or checked with a multimeter. If wiring and battery are good but starting remains inconsistent, the switch is a likely suspect.

• Look for inconsistent starter response or no-crank with dash lights on
• Test battery voltage and starter solenoid before replacing parts
• Use a multimeter to check continuity through switch positions if possible

Who is this for: The Standard Motor Products US130T is intended for professional mechanics, automotive repair shops, and experienced DIYers who need an OE-style ignition starter switch that fits vehicle-specific applications. It's a practical choice when the starting system behaves irregularly and the fault-tracing process points to the switch or when original equipment replacement is preferred for dependable performance.
