Latching relay with low voltage on off indicator

[Dustin Yoder]

I would like to find a latching relay with low voltage on off indicator. basically I like the ge RR-7specs, but I want to be able to know if it is on or off using microcontroller. The relay is switched by hand as well as by controller, so we can't keep track of state. Any ideas?

Can you not take a signal from the contacts, if high voltage there, drive an aux relay?

Specify at the machine or on the controller?need more specifics

Yes, but I want to this as cheaply as possible. could this be done for $2 or so?

Red and green led?
