Abstract
A flasher switch of the type for flashing automobile lamps is provided with outage indication consisting of a split capacitor or two parallel capacitors connected in series with one of two coils producing opposed magnetic forces in a core controlling the operation of the switch armature. The contacts controlled by the armature are held closed by discharge of the capacitors through the coil. Upon detection of a decrease in current being flashed below a predetermined value one of the capacitors is prevented from discharging, thereby abruptly increasing the flashing rate.
