This is the most useful circuit I have ever
used. It causes the relay to "latch" or stay
energized once it is activated until the
current is removed.
The above shows how a second relay can "unlatch"
the first. This diagram
shows an insulated rail instead of a magnetic
reed switch.
This is a low tech remote control that also
can be used to activate an uncoupling track, or any device.
Pushing the door bell button will remove
power from the track, just as if the 'direction' button
on the transformer was depressed. The
wire to the remote can easily be 25 to 30 ft. or longer.
