Electronic Map

Step 10 Adding Terminal Screws to the Board

Three machine screws provide points of connection, or terminals, for the map's electronic components. Two of these screws should be positioned to the left of the button labels, and one should be placed directly beneath the button labels.

1. Using a screwdriver, puncture the foam board at the location of each of the three terminal screws.

2. Add the three machine screws, securing each with a washer on top and a nut on the bottom, as shown in Figure.
