Abstract
The switch apparatus with luminous indicator device is claimed to be visible in the dark and to avoid its search for touch. The device object of this claim is to derive between the terminals of the current circuit breaker a circuit composed of a Neon gas lamp at reduced pressure and a resistance (to prevent its disablement), which are housed inside said switch. When the switch is closed, the circuit formed by the lamp resistance is shorted by the switch and the lighting lamp is turned on; on the contrary, when the lamp is turned off, the lamp is opened by opening the switch, the circuit is closed by the resistor and bulb, producing effluvia in it and illuminating the switch cover.
