Abstract
An actuating fixture for use with a push-pull switch comprises a push-pull button through which a tightening screw extends axially, and a clamping tongs which can be closed by the screw. In its operational end position, the tongs grips an actuating head of the switch below an annular flange of the head. The push-pull button projects from a collar portion of a protective housing, and the collar portion and a casing of the switch bear external threadings which are both of the same type and diameter. The push-pull button is connected with the end of the protective housing facing toward the switch by means of an encasing hose of water-tight, flexible material. The actuating fixture has an internal threading which can be screwed on to the aforesaid external threading of the switch casing. The actuating fixture can then be affixed in a switchboard by means of the aforesaid external threading of the collar portion in the same manner as the switch casing could be affixed in the switchboard by means of the said external threading of the switch casing.
