Document Type and Number:
WIPO Patent Application WO/2017/096702
Kind Code:
A1
Abstract:
A contact system employs a rotating bar mechanism (1) to drive a movable set of contacts (5) to engage with a left or right set of contacts (24, 25) respectively on two sides thereof, so as to achieve indication of an open positon or a closed positon. Particularly, a rotating shaft (2) along with a starter plate (3) and a quick-action plate (4) on the rotating shaft (2) are driven by the rotating bar (1) to change a motion trajectory of a roller (10) on a shaft (12) of the movable set of contacts, thereby achieving, aided by action of a quick-action claw (11) and a tension spring (9), quick action of the movable set of contacts (5), and realizing a contact with or disconnection from a stationary set of contacts (6) to achieve indication of the open position or the closed position. The system has a simple structure and a small size, responds quickly and accurately, and is cheap to manufacture, install, and maintain.
