Are you using DCC? If so, a change to live frog is the way to go.

With insulfrog, you could just bond the switch rail to the stock rail, to permanently make the rail live so you are not relying on the 'tab' contact, but then comes the next problem if using DCC: every now and again a wheelset will bridge the rails at the crossing, and if this happens at low speed the command station trips out. Faster passes won't trip the system, but after a while the spark erosion will be very apparent on the rail surface.
