In the normal condition, 5 Volt is connected with the Arduino, but when the limit switch is pressed the ground is connected with the Arduino’s pin number 2. As an object (or target) makes contact with the operator of the switch, it eventually moves the actuator to the "limit" where the elec-trical contacts change state. For each capacitor, connect the negative leg to the ground rail, and the positive to one of the limit sense pins on the controller. The basic micro limit switches are available in different case styles and with different operating levers. Therefore, each limit switch Black, 3-pin connector plugs into the header with the Green wire to the upper pin and the Black wire to the lower pin. When wiring limit switches to the breakout board, generally NC (Normally Closed) are connected in series (acts like a wire that when broken, breaks the circuit). A limit switch detects the physical motion of an object by direct contact with that object. Both limit switches have two sets of contacts (1 NO + 1 NC). Then as shown by the green line above bring the Z-Limit-Switch wires up the X-Plate-Back, and feed it through the X-Drag-Chain. First connect power and control sources.
