Switch arrangement for electric instrument operating at high voltage

摘要

The switch arrangement includes an operating key (12) which is activated outgoing from a rest position over an intermediate position opening or closing a first switching contact (8), into a final position opening or closing a second switching contact (9). A pressure transmission element (13) common to both switching contacts extends crosswise to the movement axis (17) of the operating key.

A pressure transmission element (13) common to both switching contacts extends crosswise to the movement axis (17) of the operating key. The operating key borders at least in its intermediate position and in its final position, at one side of the pressure transmission element, and comprises a first pressure surface area (15) for effecting the first switching contact, and a second pressure surface area (16) effecting the second switching contact, at its other side averted from the operating key.
