A Catch Diode for Soft Start Switches

Use this at your own risk.

If you accidentally turn the standby/delay switch off with the unit running, D3 will usually keep the switch from seriously arcing. Most switches will eventually fail if used over their rated voltage. That is one reason why I like to use FETs for standby/ delay switches. FETs can be picky, but if designed right, they last practically forever.
