Switching device with floating dual interrupt rotary contact has contact springs on bearing bolt on contact part that exert torque on both sides of contact part, symmetrically load end contacts

摘要

The device has a switch drive per pole rotatably mounted in bearings in an insulating housing with two fixed contact parts, a floating two-armed rotary contact part with end contacts that interact with the fixed contact parts and two contact springs with drive elements and supporting elements. Both springs are mounted on a bearing bolt on the contact part and exert torque on both sides of the contact part that symmetrically loads the end contacts. The device has a switch drive per pole rotatably mounted in bearings in an insulating housing with two fixed contact parts (26,28), a rotary contact in the form of a floating two-armed contact part (14) with end contacts (22,24) that interact with the fixed contact parts and two contact springs (42,44) with drive elements and supporting elements. Both contact springs are mounted on a bearing bolt (21) on the contact part and exert torque on both sides of the contact part that symmetrically loads the end contacts.
