Combination switch/fuses

Postby gammaxy » Thu Oct 17, 2013 11:53 am

I've been wondering about using combined switch/fuses on my panel for simplicity.

I found some that look like a typical rocker switch and automatically switch to "off" on overload. The obvious downside is you don't have any information telling you the circuit was overloaded and you might switch it back on thinking you simply forgot to turn it on.

Does anyone have a similar setup or foresee this being a problem with the inspector?

Here is the product I have in mind:

We had a similar switch on our tow reels at Harris Hill where I used to tow gliders. You would flip the switch on in the pattern once you were below 100 mph and were supposed to turn it off when it was retracted. Easy to miss, when the motor stalls for a bit the switch trips and you can hear it at least at idle power. In the 140 project I was doing I used a bunch of these, especially for landing and taxi lights:

I see nothing wrong with the approach.
