Heavy Duty Limit Switches
Built for precise industrial control
The EA800 series delivers rugged snap-lock switching for harsh environments, offering neutral position and maintained position cam options with bronze or aluminum enclosures and a wide range of certification-ready features.
High-performance limit switch technology, engineered for reliable industrial use.
Designed to withstand hazardous locations and heavy duty applications, the EA800 series uses cam-type SNAP-LOCK® technology for dependable contact action, flexible lever motion, and compact installation.
Standard EA800 switches are supplied with the combination B1/B2 cam, supporting CW and CCW action with both single action and double action modes.
The neutral position cam is ideal for applications that require the lever and cam to return to a defined resting state after operation. Maintained position cams are available for stable contact hold in one or both directions.

A cleaner spec layout for fast reading and better alignment.
