Horizontal Mechanical Limit Switch Module with Cable

A limit switch does one simple job with total mechanical reliability: it physically closes or opens a contact the instant a lever is pressed, marking a precise mechanical position without any calibration or drift over time the way an optical or magnetic sensor might develop. This horizontal-mount version is built specifically around the lever orientation 3D printers use for their axis endstops, though the same reliable physical trigger works for any project needing to detect a hard mechanical limit.

A built-in 1-meter cable means it's ready to connect straight to a controller board without sourcing or soldering separate wiring, and an onboard indicator light shows trigger state visually - useful when tuning endstop position during a printer build or repair. Rated for 125VAC at 1A, it comfortably handles low-voltage signal switching duties rather than any significant load.

Common uses are 3D printer axis endstops (X, Y and Z homing), CNC router travel limits, and any DIY mechanism needing a dependable physical trigger at a fixed travel position rather than a proximity or optical sensor.
