An item designed to act as a switching or triggering device by means of a disruptive discharge of electricity (a spark) between the electrodes. The insulation (usually air) between the electrodes is self-restoring after passage of the spark. For spark gaps used as a protective device, see arrester, electrical surge. For items with additional circuitry which perform complete modulation functions, see modulator, radar.
