ABSTRACT OF THE DISCLOSURE A vacuum switch with reduced interfering fields in the contact gap has an evacuated cylindrical envelope containing two contacts which make electrical contact in the closed con- dition of the switch and are separated by an electrically insulating gap in the open condition of the switch, the gap being symmetrically disposed with respect to the central axis of the cylindrical envelope. An electro-magnetic coil is disposed coaxially around the envelope and connected in series with the contact elements when the switch is closed producing an axial magnetic field in the region of current passage between the contact elements. One end of the coil is connected to a first conducting joining ring connected to an electrically conducting cylindrical envelope coaxially surrounding the coil and the other end is connected to a second conducting joining ring connected to a conducting disc in a central bore of which a central conductor is mounted carrying one of the contacts. One end of the cylindrical envelope extends beyond the second ring and is connected to a disc-shaped conducting base, in a central bore of which a further central conductor is mounted carrying the other contact insulating material being provided between the electro-magnetic coil, the second joining ring and the envelope as well as between the conducting disc and the disc-shaped base.
