Or you can use a polyfuse. This will remain open until the fault is cured.

Of course when there is a fault, it behooves one to register it so that the problem can be corrected.

Problem with Polyfuses is how do you mount
them in an airplane? They have to be free
to get hot . . . that's what triggers their
current reduction behavior. They're designed
to solder onto an etched circuit board.

Mounting them in a mechanically robust configuration
while letting the body of the device hang out
in the breeze is problematic.

I was tasked twice to look at Polyfuses at
Beech over the years . . . they just didn't
lend themselves to airframe integration. Inside
some black box was okay . . . but we just couldn't
figure a way to use them economically on the
bus structures.
