I'm currently having a problem with my relay.

Approximately 20% of the time I try to energize the relay, the relay will
begin to chatter and not work correctly.
Since my circuit utilizes a simple latch network, I first thought it might
be a feedback oscillation problem, but
after looking at my circuit, didn't really see any possible problem.

Here is my schematic:

Anyone see a problem, or could this just be a faulty relay???

Any help appreciated.

Thanks
