Experiments showing the use of capacitors in reducing or removing sparks from DC switches and contacts. This prevents the contacts burning and then not working. The exact valus is not required, but it depends on the DC voltage and the current. In this case 50v at 20 Amps (1 kilowatt). The capacitor value would need to be above 1000 micro farads and at a voltage above battery voltage, say 100v minimum to reduce the possibility of failure.
