Heavy Duty
EA700 Series Limit Switch

The versatility of SNAP-LOCK® Technology is gained through the use of series of uniquely designed cams in the Heavy Duty EA700 Series Limit Switch. This limit switch series features a cam and cam mechanism which allow bi-directional operation and generous over travel. One of our most popular limit switch series, the EA700 Series features either one normally open and one normally closed (1NO/1NC), two normally open and two normally closed (2NO/2NC) or three normally open and three normally closed (3NO/3NC) circuits.

The EA700 Series limit switch is engineered with Cam Type SNAP-LOCK Technology in a die-cast zinc housing for corrosion resistance. Its heavy duty cam operation allows for fast contact action. Another key benefits of the EA700 Series is its flexibility of motion, clockwise and counter-clockwise operation options, and its light operating torque. This series is available in standard, wide or long mounting.
