You are the MAN!!!  I owe you a cold one. Assembled and bench tested. All seems good. Next is a test in the real world. Have high hopes.

Bill----Thanks for all your help.

It works great!!! I installed the board in a plastic box. This is going to be mounted outside under hood. Should/can i encapsulate/pot with epoxy? Just to avoid  vibrations/ heat/water ect. I dont know if the 170 needs to be air cooled.

Thanks Bill

If you just seal up the assembly to keep water out it should be fine- if you wanted to you could encapsulate things, but it isn't really necessary if your solder connections are good. I'd leave it open for a while so it could be tweaked to change values if necessary.
The BS170 won't generate much heat since it's acting as a momentary switch and it shouldn't have problem with temperature if your plastic box isn't in danger of melting where you mounted it.
