Yes-- if the output sticks 'on' the coil fries (maybe- with almost 6x normal dissipation) and the relay drops out.

Damned sticky relay deserves to die. Makes an example for other relays.

2 TL431s, 7 resistors, a zener AND a fet. You could build a bit of very basic testgear with that lot.

All totaling about 5% of the wholesale price of a single relay, I'd reckon.
Must be from the Republican school of "deficit-reduction." With what we've cut on social programs so far we should be able to cover at least
37 minutes of the DoD's operating costs!
What does it cost to place every one of those components?
