A new circuit is described which has applications for operating high speed electric counters by gaseous triodes. No auxiliary contacts are necessary, and the circuit resets itself in a period which is so short that most counters will operate near their maximum speed. The circuit thus has the advantage that it utilizes the trigger action of the gas tube to operate with a very short initiating impulse, and yet does not involve any auxiliary relays or contacts to open the arc circuit after the count has been registered.
