Many thanks for the clarifications. One last time...in summary, if I am switching a 48VDC, 10A inductive load then I can do with a properly rated electromechanical relay right? I am thinking of the 40A, T92 series board mount DPDT relays from TYCO electronics. I will be controlling the coil of the relay using a simple toggle switch that will be mounted on the front panel of an instrument.

Touchton I had a summer job as a porter at a camp in Maine. The porters were called "Sherpas" from the people that live in the Himalayas. My uniform shirt had my title and first name => Sherpa Doug. In college I got a reputation for helping people move furniture and other large awkward objects. That combined with the shirt caused the name to stick.
