Faller Car System Vehicle Circuits

The circuit shown above is the ‘standard’ circuit found in most Faller Car System vehicles.

The charging socket has the -ve wire connected to the outer pins. This means that it does not matter which way around the plug from the recharger is connected, the +ve always connects to the centre pin and the -ve to the two outer pins.

The charging socket is connected direct to the battery.

Many vehicles have a resistor connected between the battery +ve and the reed switch/power switch/motor. This is to reduce the speed of the motor.

The reed switch is used to stop the vehicle over a suitable magnet. Note that when the reed switch is operated both sides of the motor are connected to the battery‘s -ve terminal. This has the effect of braking the motor and providing a quick stop which helps avoid the vehicle overshooting the magnet and regaining power.

The circuit shown above is a revised circuit that provides two LED brake lights that come on when the reed switch is activated to stop the vehicle.

There are a number of changes to the standard circuit to accommodate this.

Firstly the power switch is connected before the reed switch. This ensures that if the power switch is off the LEDs cannot be accidentally switched on.

The reed switch is wired differently. Whilst you gain the brake lights the braking effect of connecting both sides of the motor to the -ve battery terminal is lost. Normally this will not affect performance but if your vehicles run particularly fast or your magnets are not situated in the correct position it may be possible for a vehicle to overshoot a magnet.
