While i'm not 100% sure they will increase the contact life of a relay, they are required for triac use to properly shut off triacs with inductive loads. | |

I don't know if it would apply to your situation but you might want to look into TRIACs; these are like solid state switches that can be switched at the zero-crossing of the AC waveform. I don't know if they're the right solution but I thought I'd mention as something to look into. | |
