To settle a friendly argument I would like to build a tester that would stress mechanical switch contacts until they fail. There will be a counter to keep track of switch operations. Some sort of control over the intensity of the arc would be required so that I can chose to kill the contacts over a period of days, or weeks depending on the results I get.
Can you suggest a circuit that would give a reasonably constant arc over a mechanical switch?
I am only stuck on creating enough inductance to give an arc. The method of counting operations and timers etc is of no importance just now.
All ideas welcome.
Cheers
