Abstract (en)
[origin: WO9003657A1] In a vacuum switch tube (10) designed specifically for use in a load-break switch, the coaxially facing contact pins (4, 5) are made of chrome nickel steel; the front faces of the contact pins (4, 5) form the contact surfaces. This vacuum switch tube (10) is designed specifically for the function ''switching off the load current''. For this purpose, the contact of the vacuum switch tube (10) is closed just before a parallel switch contact (12) opens.
