The first momentary switch is connected to the power supply of the circuit. By pushing the cardboard-button, the inside alu foil is touching alu foil and closes the circuit, the motors ~~are on/off~~.

The first momentary switch is connected to the power supply of the circuit. By pushing the cardboard-button, the inside alu foil is touching alu foil and closes the circuit, the current flows and the motors run.

The second momentary switch works the same way, but is connected to a DPDT-relay. When metal ~~touches~~ metal the polarity ~~reverses~~ which changes the direction of the attached motors.

The second momentary switch works the same way, but is connected to a DPDT-relay. When metal is touching metal the polarity gets reversed which changes the direction of the attached motors.
