PROTECTIVE SWITCH |
摘要 |
The apparatus of the invention comprises a case housing a fixed contact and a mobile contact carried by a pivoting lever, with resilient return to the closure position, a rocking lever adapted for acting on the pivoting lever in the opening direction in response to an electric fault and a manual control member connected to the pivoting lever. A single spring exerts on the pivoting lever a first torque in the closure direction and on a drive piece blockable by the rocking lever a force adapted to generate on the lever a second torque antagonistic to and greater than the first one. With the manual control member a third torque antagonistic to and greater than the first one is exerted on the pivoting lever. |
