If you have 1122(E) switches, you will need 2 plastic fiber insulating pins in the correct locations for each switch to keep them from being actuated constantly(the one-year-only 1122 switch requires no fiber pins):
The left hand switch uses the same rails(the short, inside ones) in mirror orientation.
Also, be sure not to let any part of the train park on those control rails(with the pins) of the switch while the track power is on as this can overheat the switch motors(solenoids).
For reference, this is what 1122(non-"E") switches looks like:
