I require a SPDT relay (changeover) that will switch up to 600Vdc, which presents some problems because on the major suppliers such as Digikey, such a product is not readily available at such a high voltage.
However, there are SPST relays available and I was thinking of using two of those. However, I am concerned because I need the contact to the first line to disengage before connecting to the second line (otherwise I might cause a short).
To make things a little more difficult, I have only one digital control signal available, and would like the switch to connect to either one line or the other based on whether I am outputting a logic 0 or logic 1.
Anyways, all this to ask: does anyone have any recommendations for introducing this switching delay via hardware components? I was looking around for a "break-before-make" design but wasn't finding much luck.
Any help or direction would be appreciated!
Edit: Based on the accepted answer here is the schematic I came up with, for reference. Thanks everyone!:
