<p>The stationary contact clamping screws are secured on the outside of the contactor switching chamber (90). The latter has, at least on one side, lugs (94a, 94b) and apertures (108), suitable for securing positively an additional switching device. Preferably the lugs are formed on long edges (94b) of a wall (94), covering the chamber. In this manner the lugs are typically blade-shaped, parallel to an aperture (106) for a contact bridge plough. The chamber aperture (108) is thus located between the blade and the contact bridge plunger aperture, directly in the chamber wall.</p> |
