This set will give the impression of a right on technical joystick. There is only one hole for an on and off switch in the top plate. The hole for the display is also missing. You can decide how many and where to put extra holes for more switches. You can also decide to make a hole for a display, maybe not the suggested display but another, for example a dog display. Note that the plate that will be fitted inside the plastic Hammond box just beneath its top have all holes pre cut. So there is simple guidance if you want to use these positions for your own choice of holes.
