Bob,



My circuit requires a DPDT "on-on-(on)" switch action with a

make-before-break between center and momentary positions.  Does the

S700-2-50 switch fulfill the make-before-break requirement?  If it doesn't, do you know of a source for such a switch?



Thanks for all your help via the Aeroelectric list.  I'm a loyal lurker.

   The switch mechanism is a "teter-toter"

   rocker that can only break the present connection

   long before the open contacts close. I'm

   not aware of any toggel switch that would operate

   any differently.

Jim,

Perhaps additional components can be used to delay opening of the DP3T switch contacts while switching from one position to another.  A large capacitor might help, depending on the current of the load.  Or a relay can be used with its contacts in parallel with the DP3T contacts.  See the attached sketch.  http://tinyurl.com/ya5zkkv

If you post a copy of your schematic, others can offer suggestions.
