A compact roller-lever snap-action limit switch for homing and end-of-travel detection, with onboard power and trigger indication.

Choose the required limit input and set SW-VCC to 5 V where the controller provides that selector.
Follow the three labels above. The microswitch terminals are already handled by the module; use its 3-pin connector.
Move the roller lever by hand. The trigger LED and selected controller input should change, then return reliably when released.
