| 摘要 |
The invention relates to a rapid tri-state bidirectional switching device with three switching states of forward, backward and idle connection positions, comprising a shell (1) and a movable electrode (2) arranged within the shell (1) for switching among the three states, wherein the movable electrode (2) is provided with a movable contact point (4) at either end thereof, the shell (1) is provided with a fixed contact point (5) at the front and rear sides thereof respectively corresponding to the movable contact points (4), a driving solenoid shaft (18) is arranged above and connected to the movable electrode housing (3), and provided with a front locking notch (11) and a rear locking notch (12), the device further comprises a release lock (9) cooperating with a front locking notch (11) and a rear locking notch (12) to lock the movable electrode housing (3). The rapid bidirectional tri-state switching device is advantageous for its short switching time, small volume and reliability in contact. |
