Japanese Patent JP2004516619
Kind Code:
A
Abstract:
The invention relates to a contact arrangement for a vacuum switch tube for low-voltage power switches. The aim of the invention is to reduce the contact force required to control short circuit currents. To this end, a twin-contact contact arrangement is used wherein every contact comprises a plurality of separate individual contacts having a defined spring rate. At least one of the contact bodies ( 4 ) is configured as a two-layer spiral contact with a lower layer consisting of a highly elastic material and an upper layer ( 7 ) consisting of a highly electroconductive material. A contact coat ( 9 ) consisting of a contact material is provided on the upper layer in the outer zone of every contact arm ( 10 ).
