Electrical spring force terminal has transverse arm on rotary shaft with control surface with increasing curvature in contact with spring leg pressed into open position when shaft operated

摘要

The device has at least one clamp point for connecting an electrical conductor and an insulating housing for attachment to a mounting wall or device. A shaft is rotatably mounted in the housing next to a flat spring leg (20). A transverse arm attached to the shaft has a strip-shaped control surface leading away from the shaft with radially increasing curvature in contact with the spring leg, which it presses into its open clamp point position if the rotary shaft is operated.
