How's this for an automatic overcurrent circuit? RL is whatever load it's connected to, while Vswitch, Rswitch, and Qswitch would be replaced with a tactile button. The zener diode is less than ideal, but I don't think replacing it with a 3.3V linear regulator would be difficult. The LED turns on when the FET has latched off from overcurrent. I could equally build one for a positive voltage rail as well as the negative one, in the case I've a ground in between the two well.
