摘要

Engine plug-and-socket (20) has earth connection, earth terminal, zero-leader connection and zero-leader terminal located in contact with each other. Socket (40) contains second earth connection and second zero-leader connection and plug (30) contains second earth terminal and second zero-leader terminal. Earth and zero-leader connection and phase connection as well as phase terminal and earthing and zero-leader terminal are so arranged that either first phase terminal engages at first phase connection and second phase terminal engages at second phase connection or first phase terminal engages at second phase connection and second phase terminal engages at first phase connection. An independent claim is also included for an arrangement especially a jalousie or roller-shutter casing.
