Choosing an industrial limit switch means balancing actuation style, electrical ratings, physical size, and cost. The four switches here span a wide price range, from a small Omron micro limit switch at the low end to a Cutler Hammer industrial unit at the top. Your job is to match the switch to the circuit you are controlling and the environment where it will live.
Quick take
At a glance, the Omron SS-5GL is the budget-minded starting point, while Square D 9007-CO3 raises the electrical specification to 10A at 600VAC. The Allen-Bradley 802T-NP is the model to evaluate for machine-tool and coolant areas, and Cutler Hammer 10316H16C serves applications that need a roller actuator and a robust body. Prices range from just over $12 to just under $180, so your budget will rule out some of these options before you even look at actuation.

Product notes
Lot (2) Omron Micro Limit Switch SS-5GL with Straight Lever 5A 125VAC #E66AB
This lot delivers two Omron micro limit switches with straight levers, handy when you need a spare or want to sense two positions. Each switch is rated 5A at 125VAC and 3A at 250VAC, with single-pole double-throw contacts and three solder terminals for common, normally open, and normally closed wiring. The straight lever is an easy actuator for cam or slide detection, and the two-pack gives you a backup or a second sensing point. The operating temperature range is listed as -25°C to 85°C, and the mechanical and electrical life is specified at 100,000 cycles. The limitation: the 125VAC rating and solder-terminal wiring point to low-voltage control circuits rather than high-power line loads. At $12.95 for two, it is the least expensive way into this group.
Square D 9007-CO3 Industrial Basic Snap Action Limit Switch 10A 600VAC
The Square D switch is rated 10A at 600VAC, a significant step up from the Omron's 5A at 125VAC, and it uses a double-pole double-throw, double-break contact configuration. That DPDT-DB arrangement gives you multiple contact sets for interlocking or signaling. It has a brown housing with a black plunger, and the terminal block accepts 22 AWG to 14 AWG wire. It is built in the United States. The mid-range price of $52.89 puts it between the Omron and the higher-priced Allen-Bradley and Cutler Hammer units. The main trade-off is condition: this is listed as new open-box stock rather than a sealed retail unit, so inspect it when it arrives if packaging condition matters to you.
New 802T-NP For Allen-Bradley 802T-NP Oil Tight Limit Switch
This is a new oil-tight limit switch, and the oil-tight construction is the main reason to consider it. It is designed to keep cutting fluids, coolants, and moisture away from the contacts, which makes it a suitable choice around machine tools and processing equipment. The model 802T-NP is listed as new and made in China, and the $140.00 price places it above the Omron and Square D options. The trade-off is cost: you are paying more for the oil-tight design, so it makes sense mainly in environments where standard switches might not survive. If your shop floor is dry and clean, this may be more protection than you need.
Cutler Hammer 10316H16C Heavy Duty Industrial Limit Switch With Roller Top Push
Cutler Hammer 10316H16C is described as a heavy-duty industrial limit switch with a roller top push actuator. The roller top lets a cam or moving part press the switch without direct finger pressure, which is useful in mechanical interlocks and industrial machinery. At $179.99, it is the most expensive switch in this comparison, so it fits applications that genuinely need the heavy-duty construction and roller actuation. For lighter control-panel sensing, the Omron or Square D units will cover the job at a much lower price. The roller actuator is especially practical when the switch is reached by a rotating cam.
Final recommendation
Choose the Omron SS-5GL two-pack when budget is the primary constraint. Pick Square D 9007-CO3 when you need a single switch with a higher electrical rating. Select Allen-Bradley 802T-NP for an oil-tight application. Opt for Cutler Hammer 10316H16C when a roller top push actuator is required.
