The drilling system in Figure Q2 has the following functions: move a work piece into position, clamp it, start the drill, move it down to drill a hole through the work piece, back the drill out, turn the drill off and delay for 1 minute before repeat for a new work piece. Start button and limit NO type while a stop button is NC type. The system is activated using the start button and the stop button switch is used to deactivate the system and turns on a red light.
