interrupter

One that interrupts.

A device that periodically and automatically opens and closes an electric circuit, producing pulses.

One who or that which interrupts. Also interruptor.

Specifically— In electricity, any instrument for interrupting an electrical current, as the automatic arrangement used with the induction-coil.

In milit. engin., an electrical device which forms part of a system of apparatus for determining the velocity of projectiles, used in connection with wire targets and chronographs. The passage of the ball or shell through a target serves to interrupt a closed electrical circuit, and thus release the automatic registering mechanism of the chronograph at the instant of passage. Often a number of targets are used, placed at accurately measured and uniform intervals in the path of the projectile, and the registered data serve as a basis for determining the variation of velocity in different parts of the path.

One who, or that which, interrupts.

A device for opening and closing an electrical circuit; a vibrating spring or tuning fork, arranged to make and break a circuit at rapidly recurring intervals, by the action of the current itself.

One who or that which interrupts.
