An electrical switching device comprises a contact point having two double-break contacts, a contact link having a width, a contact pressure spring exerting a pressure on the contact link, a striker pin configured to act on the contact link counter to the pressure of the contact pressure spring during a switch-off operation so as to move the contact link into an open position, and a thruster actuatable by a switching mechanism and configured to guide the striker pin, the thruster having two limbs projecting in the same direction towards a free end of the thruster so as to form a slot there between, wherein a distance between the two limbs tapers towards the free end such that the distance at the free end is smaller than the width of the contact link, so that the contact link is clamped between the two limbs during the switch-off operation.
