1. An electric switch, comprising a carrying member movable along a predetermined path between switch-opening and switch-closing positions; a first current-conducting carrier mounted on said member and having a first electric contact and exposed end and lateral surfaces; a second current-conducting carrier mounted on said member for movement relative to said first carrier and having a second electric contact, said second carrier at least substantially surrounding said surfaces of said first carrier; first and second complementary electric contacts respectively located in the path of said contacts on said first and second carriers during movement of said member toward said switch-closing position; and resilient means operating between said second carrier and said member to maintain the contact of said second carrier in such position with reference to the contact of said first carrier that the contact of said second carrier engages the second complementary contact prior to engagement between the contact of said first carrier and said first complementary contact during movement of said member toward said switch-closing position. |
