Abstract

A fuse-type circuit breaker having a fuse link which is manually pivotal in a housing between an on position and an off position. The fuse link has contact caps which, when in the open position, short-circuit two current contacts which are fixed to the housing. Also provided is an operating state indicator device which includes a light source for the fuse link. The indicator device, at least in the on position, is electrically connected with the two contact caps of the fuse link and with the two current contacts. The indicator device is in parallel with the latter and is provided with a very high electrical resistance relative to the fuse link. The indicator device is in the form of a blinker which incorporates a capacitor, a first diode connected ahead of the capacitor, and a charging resistor as well as a glow lamp connected in parallel with the capacitor and in series with a discharging resistor.
