Today, manual control of a switching device located at a pole is implemented for instance by means of a rotational crank provided at the end of a control tube. Such a crank is, however, visible at all times and thus easily invites vandals. In the hand guide (1 of the invention, unauthorized control of the switching device is prevented in such a manner that the crank, i.e. the control arm (5, provided in the hand guide can be inserted into the centre and into the control tube (7, where it can be locked. 主权项： 申请日：1997-05-23 公开公告日： 1997-05-23 分类号：H01H3/00 发明设计人： TIITOLA, TAPANI; LEHTONEN, KAARLO 申请国代码： NO 优先权： 19941125 FI 945565; 19951121 FI 9500642 摘要附图：
