Abstract
The invention concerns an on-off switch (1) for high-frequency currents. This switch (1) comprises a housing (2) made of an electrically non-conducting plastic and sealed at both its upper and its lower sides by electrically conducting contact parts (3,4). A metal bellows (14) is present in the housing (2) and is connected at one end to one of the contact parts, (4) and at its other end to a contact head (25). Using compressed air, the contact head (25) can be moved to make contact with the other contact part (3) or be removed away from it.
