<p>The electrical switching device (1) has a double contact point (10) and a contact bridge (7), which is passed by an impact pin (20) against the pressure of a contact pressure spring (11) during a striking operation in opened position. The distance of the two brackets is tapered to each other at free ends. The distance at the free ends is smaller than the width of the contact bridge such that the contact bridge is jammed during a disconnection between the brackets. A pusher (12) is operated by a latch (15), in which the impact pin is guided.</p> |
