SW513 is not a standard Leviton electrical device code—it is actually a Duralast automotive A/C (pressure) switch part number, not a wall switch or wiring device.

What SW513 is

• Type: Automotive A/C pressure switch
• Brand: Duralast (aftermarket auto parts)
• Use: Controls vehicle air conditioning compressor operation based on refrigerant pressure
• System: HVAC in cars (not building electrical wiring)
• Typical application: Safety switch that prevents compressor damage if refrigerant pressure is too high or too low

Key point (important for your list)

Even though it looks like a “switch code,”:

• ❌ It is NOT a wall switch
• ❌ It is NOT a Leviton electrical device
• ✔ It is an automotive sensor/switch used in A/C systems

Why this matters

Your other items (T5320, T5825, THHN wire, receptacles, etc.) are:

• electrical building materials

But SW513 belongs in a vehicle HVAC/engine parts list, not electrical inventory.

Simple takeaway

SW513 = automotive A/C pressure switch (car HVAC part), not an electrical wall or lighting switch.

If you want, I can separate your whole list into:

• electrical rough-in (wire, breakers, boxes)
• devices (receptacles/switches)
• HVAC/electrical equipment
• non-electrical misc/automotive items

That would clean up your catalog a lot.
