I wish I had come across Heisener first, no one could help me for 2 days. You are now saved into the TOP of my favorites web list. Thank you very much.

All current moves in switching devices with the proper selection of amp rating capability. I chose these to do a job that had to handle only 1/3 of it's rated capacity. So they were the perfect choice. To date they work as expected; perfectly.

EXACTLY what I was looking for -- one piece with a low forward voltage drop to isolate some DC power sources. They work fantastic!
