CONTACT FUSE Russian patent published in 1999 - IPC

FIELD: electrical engineering. SUBSTANCE: device has two members, one of which is stationary and another one is mobile and has two positions. It is either spaced from stationary member or contacts it. Contact by-pass is mounted on either of two members and closes electric circuit which is mounted on another side of contact, when mobile member contacts stationary member. Said by-pass is designed as two contact pins, which are made from conducting material and are connected to each other by means of current-conducting member which is hidden in plate which is made from insulation material and is mounted on said contact member. Both pins are connected to current-conducting member by means of welding joints which have very low mechanical strength, and which are broken upon application of separation or fracture force. EFFECT: increased functional capabilities. 4 cl, 4 dwg
