Hot & Cold Switching Explained | Reed Relay Switching Methods | Pickering Electronics 

This video provides a brief explanation of what hot and cold switching is when using reed relays and the effects different switching methods can have on relay life expectancy.
One simple method to greatly reduce the damaging effects of hot switching, and greatly increase the expected number of operations, is to cold switch the signal. Cold switching can increase a reed relays life expectancy to more than ten billion operations.
The video also goes into detail about capacitive inrush, as this is another common reason for early relay failures, which can easily be avoided/resolved.
