Without putting a pencil to it, what you've outlined sounds suspiciously like a R/S flip flop (or latch) driving 2 SPST relays or SSR's. Not quite sure of your "open center" requirement though. What do you mean by "electrically controllable"? - digital logic (ie microcontroller?), or low voltage electro-mechanical? More detail required.

Just did some looking and found that DPDT solid state relays are uncommon beasts, expensive and often discontinued.
