Eaton Crouse-Hinds 2720A Toggle Switch - Copper-free Aluminum
Part Number: 2720A
Quick Summary
The 2720A toggle switch from Eaton Crouse-Hinds provides reliable surface-mounted control for industrial panels and machinery. Engineers often face corrosion and compatibility challenges when using aluminum housings in harsh environments, leading to downtime and costly replacements. This model uses copper-free aluminum to improve corrosion resistance while keeping weight and footprint minimal. It is designed for Ordinary/Non-Hazardous Locations, rated for 15A at 277 Vac, and offers both a single-pole and a three-way configuration in one compact unit. By combining two switch functions in a single package, it simplifies wiring, reduces parts inventory, and accelerates panel assembly. In addition to robust construction, its surface-mount mounting and Pauluhn interior design support straightforward installation and long service life, especially in automation panels and control cabinets.

Copper-free aluminum housing eliminates “green rot” and corrosion concerns, delivering longer service life in demanding environments. The business impact is clear: reduced maintenance costs and fewer field failures, which translates to higher up-time for critical automation panels. In practice, the surface-mount design enables faster installation and cleaner panel layouts, reducing wiring errors during assembly and allowing technicians to complete upgrades with minimal downtime. The 2720A combines one single-pole switch and one three-way switch in a single device, decreasing parts count and simplifying spare part inventories for OEMs and panel builders. With 15A at 277 Vac, this switch supports common lighting and control circuits without overdesign, improving overall system efficiency. The copper-free aluminum construction also keeps weight manageable for mounting in tight spaces, while the Ordinary/Non-Hazardous Locations rating aligns with typical industrial and commercial environments. Compatibility with Pauluhn interior toggles facilitates easier integration into existing control schemes, and the surface-mount footprint supports rapid retrofits and modular panel designs. This device addresses objections about reliability and procurement complexity by offering a durable, standards-aligned solution that reduces total cost of ownership over the equipment lifecycle.

FAQs
The 2720A is a surface-mount toggle switch designed for quick, clean panel installation. Its compact footprint (2.75 in L, 1.75 in W, 4.5 in H) fits tight panel spaces, and the unit combines a single-pole and a three-way switch in one housing, reducing wiring complexity and inventory needs during panel assembly.
The device is rated for 15A at 277 Vac, suitable for common industrial control circuits and lighting applications in non-hazardous locations. The dual-function design supports both single-pole control and three-way switching within a single unit, enabling versatile panel wiring without multiple separate components.
The 2720A carries an Ordinary/Non-Hazardous Locations area classification, making it appropriate for general industrial and commercial settings. It is built with copper-free aluminum to resist corrosion, helping maintain performance in typical panel environments without exposure to harsh or explosive atmospheres.
The switch uses copper-free aluminum, reducing corrosion risk and weight while maintaining strength for surface-mount installations. This choice lowers maintenance costs, improves long-term reliability, and simplifies sourcing since the same unit handles two switching functions in one package.
By combining a single-pole and a three-way switch in one compact unit, the 2720A reduces parts count and simplifies wiring. Its surface-mount design speeds installation, shortens assembly time, and lowers inventory overhead, delivering quicker project completion and lower total cost of ownership in automation projects.
