ABSTRACT:
The combination of a current limiting device and at least one openable isolating point electrically connected therewith, the current limiting device including a variable, pressure-sensitive solid-state resistance the resistance being variable from an initially relatively very low resistance or impedance value to a relatively very high resistance or impedance value when the isolating point is opened, the solid-state resistance being integrated into the isolating point as a switch contact member.
