Relay contact life, when switching inductive loads, will approach resistive load contact life if
suppression circuits are used. The following figures are examples of typical suppression
circuits for AC and DC loads. The 1A, 200V diode shown in the DC load typical suppression
example is an industry standard 1N4935. The resistor and capacitor shown for AC load
suppression are standard components, available from most electronics distributors.
