Cutler-Hammer LT3400T U 400 3 Limit Switch Unit

Cutler-Hammer LT3400T U 400 3 Limit Switch Unit is a three-switch limit switch assembly from Cutler-Hammer. Each of the three switches provides a discrete electrical signal when actuated by mechanical movement, allowing a control system to detect position, end-of-travel, or interlock conditions. The LT3400T U 400 3 designation identifies the model and its three-switch configuration, a compact solution for integrating multiple sensing points in a single device. In typical industrial control architectures, such a unit can simplify wiring and reduce enclosure space by combining three switching elements into one unit, while preserving independent operation of each switch. Because it is a multi-switch device, it supports multiple control paths within the same footprint, which can help streamline wiring diagrams and maintenance tasks.
