Modular control panel for wooden train components.

# Control Panel

The control panel is a simple modular circuit that contains a battery holder for two AA pencil batteries, a main switch, and several switch modules. The first module is connected to battery power through the switch, and subsequent modules are connected in parallel. Each module contains two microswitches and an output connector (terminal). The controller switches one or the other microswitch, changing the polarity of the output voltage.
