CNC router limit switch, also called cnc limit switch or cnc home switch, is one type of inductive proximity sensor. Its function is to stop each axis of cnc router (XYZ) at the coordinate of home point accurately during the operation of Go home. That’s why it called home switch also. 

How CNC Router Limit Switch System Works

The system is consisted by two parts, cnc limit switch and small steel chip. Small steel chip is fixed at home position and cannot move; cnc limit switch is mounted near the drive motor of each axis and can move. In operation of Gohome, cnc limit switch is moving to the steel chip, when it close to the steel chip and reach a certain distance of 4mm, the steel chip will be detected by the cnc router limit switch and the switch will actuate to send out signal to the controller, then controller stop the machine.
