Further displacement of holder 5 makes contact strip 6 change its inclination angle relative to horizontal end of fixed contact 3 until it is brought in contact with the latter. In the process contact strip 6 moves relative to fixed contact 3 due to bevel 7 on holder 5 with the result that both rubbing surfaces are wiped. Disconnection of device causes reverse displacement of contact strip 6 relative to fixed contact 3, further change in its inclination angle, and disengagement from fixed contact 3. |
