Turn Normal Relay into Latching Relay

[Kedar264]

Turn normal electric relay into latching relay only using neodymium magnet

Just open the relay and stick an neodymium magnet on to common terminal and that's  all.....!

You can use this latch  as memory,  switch, etc.

This Modified relay doesn't need continues power ,input pulse is sufficient to latch the relay in one of the two states.

Nice mod, just will be a little vibration sensitive. If you use a larger relay ( plug in type) you might be able to do it and put the cover back on as well.
