The ignition switch for a vehicle such as a lawn and garden tractor is connected directly to a printed circuit board which also includes interlock systems components. The circuit board with the switch and other components is wave soldered in an automated process to make good electrical connections for reduced voltage drops, thereby reducing the number of relays required. Wiring harnesses are also soldered directly to the board during the soldering step. In the preferred embodiment, the ignition switch is fixed to the board and supports the board from the console of the vehicle. However, if the switch or another component on the circuit board needs to be remotely located with respect to the remainder of the board, the switch or component is mounted on a break-away section of the board, and the wires connecting the board sections are soldered with the remainder of the components during the automated process. After the board is manufactured as one assembly, the section is snapped apart from the remainder of the board, and the board and break-away section are mounted at the desired locations on the vehicle.
