Doigt (Panneau électrique)

[indianfrench]

How can I translate "doigt" in this context?

Here we are taking about panels of Low Voltage Switch Board.

Ce panneau est constitué par une plaque isolante sur laquelle sont disposés des doigts qui viennent s'introduire dans la mâchoire côté départ lorsque le panneau est en place, fusibles enlevés.


My Guess--
This panel is made of insulating plate on which Fingers are arranged which opens the feeder side clamp when the panel is in place, fuses removed.

Please help me ...

Thanks
