That's as reasonable an idea as any. However, the service life specs for that relay rate it at 10^8 operations. I probably average six doorbell assaults per week, so taking leap years into account that relay should last 319,416 years: =(10^8/6)/(365.25/7)

Hmmm...that doesn't take into account that leap year skips every 100th year except on the 400th year it doesn't skip. So call it an approximation and let it go at that. smile

I know I'm getting old (turned 79 last month) but I'm not that old!
