Abstract (en)
[origin: WO9301604A1] An isolating switch is to be adapted to the heavy currents occurring during busbar changes at low operating voltages. To this end, an auxiliary contact pin (3), which is located in a counter-contact (2) in the known manner and acts as a preliminary contact, is fitted with an auxiliary sliding contact (11). The auxiliary contact pin (3) runs off this auxiliary sliding contact (11) after the counter-contact member has made contact. Thus the rated current is conducted solely along the main current track. (The auxiliary contact pin runs off the auxiliary sliding contact.)
