Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
99 words
IN AN ELECTRONIC SWITCHING CIRCUIT: A SOURCE OF DIRECT CURRENT AND A SWITCH IN SERIES; A TRANSISTOR CONNECTED AS AN EMITTER FOLLOWER WITH A RELAY IN THE EMITTER CIRCUIT; AND A CHARGING CIRCUIT CONNECTED ACROSS THE BATTERY AND SWITCH COMPRISING A LOAD, CHARGING RESISTOR, AND CHARGING CAPACITOR, THE JUNCTION OF THE CHARGING RESISTOR AND CHARGING CAPACITOR BEING CONNECTED TO THE BASE OF THE TRANSISTOR; SAID RELAY HAVING A NORMALLY OPEN CONTACT ADAPTED WHEN CLOSED TO CONNECT THE BATTERY VOLTAGE ACROSS THE LAMP LOAD; THE CLOSING OF THE RELAY CONTACT ALLOWING THE CHARGING CAPACITOR TO DISCHARGE THROUGH THE CHARGING RESISTOR.
