Choosing between these two limit switches comes down to how much protection and how much budget you're working with. Maybe you're replacing a worn switch, or maybe you're building a control panel from scratch. Either way, the choice is about matching the switch to the environment and the price you're willing to pay. In the relays, contactors, and industrial switches aisle, you'll sometimes have to pick between a straightforward limit switch and a more specialized one. This pair is a good example of that trade-off.
Quick Verdict
If your budget is tight, the Square D 9007-CO3 is the lower-priced option with a 10A, 600VAC rating. If you need a more protective housing, the Allen-Bradley 802T-NP is the listing that leans into that need, and the price difference reflects it. The two switches are really competing on different priorities: one keeps the cost down and spells out the electrical details, while the other centers on a specific model and design focus.

Product Notes
Square D 9007-CO3
The Square D 9007-CO3 is the lower-priced option in this head-to-head and gives you a clear set of electrical details. It carries a 10A, 600VAC rating, a DPDT-DB (Double Pole Double Throw, Double Break) contact arrangement, and an AWG 22 to AWG 14 wire range. The brown housing with black plunger is easy to identify, and the coil voltage is listed as not applicable (0 volts), which is what you'd expect for a mechanically actuated limit switch. The limitation is that this is a basic snap-action design, so it doesn't claim the oil-tight construction that the other product leads with. If your installation is dry and protected, this lower-priced option gives you the electrical details you need without the extra cost. That combination of price and spelled-out specs makes it easy to confirm whether the switch will fit your circuit before you commit.
Allen-Bradley 802T-NP
The Allen-Bradley 802T-NP is the higher-priced unit in this comparison and centers its identity on the oil-tight design. The title calls out the 802T-NP model number, the condition is new, and the country of origin is China. If the oil-tight form factor is essential for your machine, this is the listing that offers that feature directly. The trade-off is cost: it runs about $87 more than the Square D 9007-CO3, so you're paying for that design focus. The title and condition tell you what this switch is, and the decision comes down to whether that design is worth the higher price in your specific setup. For a replacement job where the panel already calls for that model number, the higher cost may be a secondary concern.
Final Choice by Use Case
Before you choose, ask yourself whether the switch will live in an area where oil is a real concern. If it will, the design focus of the Allen-Bradley 802T-NP starts to matter a lot more. If it won't, the Square D 9007-CO3 gives you the lower listed price and the electrical details to make a confident fit check.
- Choose the Square D 9007-CO3 when budget is your primary concern and you don't need the specialized housing of the other listing.
- Choose the Allen-Bradley 802T-NP when that specialized design and model match are worth the higher listed price.
