This Snap Relay is a very useful Track Arrangement Designed by Atlas Model Railroad.
A double-pole, double-throw electrical switch actuated by a remotely controllable twin-coil, momentary power electromagnet.
It can do all sorts of useful jobs on your layout, some of which are: -Power the frogs on Mark 2 Turnouts to eliminate the short “dead- spot” and prevent stalling of short-wheel-based locos.
-Power trackside signal lamps to show switch point settings.
-Feed control panel lamps to show points setting of remotely located turnouts.
-Selective power control for dead-end sidings with all Atlas turnouts: Mark 2, Custom-Line, or Snap-Switches.
Control X-sections automatically.
It can be installed wherever convenient.
Four rail joiners are provided.
