ABSTRACT Electrical vacuum switch having two contact members carried by contact rods for moving the contact members in and out engagement with each other, in which each contact rod is partly surrounded by a yoke of magnetic permeable material, closely adjacent each contact member, each yoke leaving a gap between the yoke legs, so that upon moving the contact members out of engagement, the magnetic flux lines, generated in each yoke by the current through the contact rods, will traverse the arcing gap between the contact members, towards the opposing yoke, resulting in a magnetic field in the arcing gap.
