FIELD: electrical engineering; high-speed switches incorporating arcing contact.
SUBSTANCE: proposed contact system has axle-mounted movable contact, fixed contact, arcing contact, arcing-contact spring, and arcing-contact movement limiter. Novelty is that switch is also provided with lever whose fastening axle is mounted on movable contact, lever spring disposed between movable contact and lever, and lever movement limiter. Arcing contact spring is disposed between arcing contact and lever. Arcing-contact movement limiter is designed for limiting arcing-contact movement relative to lever in opposite directions.
EFFECT: enhanced off-operation speed of switch.
