When I was building my black Mirage, I decided that using fuses for circuit protection was not the best idea. If a fuse blows, you'll need another one and who carries an assortment of fuses in their pocket? Even if you had ready access to a spare, you would lose valuable time getting the car repaired and back out on the track. To me, a circuit breaker that can be reset was a better choice. I found some small "Switch Breakers" made by AirPax for aerospace applications and bought one in each of the current ratings that I needed.





By adding a switch & breaker in each circuit, I can control things individually. For example, I can switch on the master power relay and push the starter button, with the ignition in the OFF position to pre- oil the engine bearings, I can switch the fire suit cooler on/off, etc. In looking on-line just now to see if these are still made, I was stunned to see that they are priced at between $600 and $2800 EACH! Good grief, I bought mine on the surplus market for probably under $50 for the whole lot. I guess I was just at the right place at the right time.
