Double-action final turn-off device for an electric drive motor, adjusts a window blind spindle between two final positions defined by end stops

摘要

A power supply circuit for a drive motor (DM) (2) has a control button for moving the DM backwards and forwards. A final circuit-breaker device (24) breaks the power supply circuit when components (12,14) reach any final position. High restoring torque acts on the DM as a component starts towards one of its stop positions. The DM swivels on bearings around its axis of drive rotation.
