Abstract

The invention relates to an electrical main switch (10) having a housing (12), having a switching mechanism (14) for operating at least one contact point (16), having a locking device (18) for inhibiting the switching mechanism (14), which locking device (18) has a blocking part (20) which can pivot and can be pivoted by means of a locking apparatus which acts in a positively locking manner, preferably a hexagonal hollow-socket key, which locking apparatus can be inserted through an access opening (13) in the housing (12) into a retaining opening (22) which is provided on the blocking part (20) and is accessible from the outside, for positively locking engagement, which retaining opening (22) is provided with a central blocking pin (24), the central blocking pin (24) being mounted in a pendulum manner by means of a spring (26) which is inserted into the retaining opening (22), and which central blocking pin (24) deflects if acted on eccentrically, the base of the retaining opening (22) being provided with a central recess (25) into which the blocking pin (24), on which the provided locking apparatus acts centrally, engages and releases a region (23) (which is intended to produce the positively locking engagement) of the retaining opening (22) before engagement of the locking apparatus. <IMAGE>
