Power switch
Most of the old equipment has power supply switch problem. The contacts arc
by electric power and need to be replaced or sand down to refinish the surfaces to prevent resistance build up. After the resurfacing surface, is there any chemical can prevent the arc again and the oxidation coming back? I am using the de-ox cleaner now, any other suggestions. Thanks Eric |
