Have the base of the pieces fit only one way into sockets on the grid square so spots for four magnets fit over the switches. Have magnets in the bottom of each piece to trigger the switches to ID the piece on that spot. I recall electronic chess boards use magnets to detect the presence of a piece then track the ID of each piece from memory. This works as one piece moves at a time and start position is fixed. With a single switch orientation and placement is not critical. | |
