| Zusammenfassung: | A manipulating mechanism for miniature breaker is characterized by that its jumper and contact arm are two-step boosting lever. Regulating their lever ratios can conveniently regulate the moving speed between contacts and the action force between jumper and lock for optimal match. A slotted cam mechansm is used to control the movement tracings of jumper and moving arm with low friction force. |
