Contacts - Arcing may occur across contacts when the contact opens and closes. This

results in electrical noise as well as damage to the contacts. Connecting a RC network

properly sized can eliminate this arc.

For circuits up to 3 amps, a combination of a 47 ohm resistor and 0.1 microfarad

capacitor (1 000 volts) is recommended. For circuits from 3 to 5 amps, connect 2 of

these in parallel. See Figure 2-5.
