摘要:
The invention relates to an electrical switching arrangement which is arranged in a switching chamber, comprising at least one contact arrangement comprising a moving contact and a fixed contact, with the fixed contact being formed on a fixed contact mount (18) which is arranged at the end (13) of a busbar (10), and, furthermore, with a contact rest mount (20) and a switching arc guide apparatus (30), which is produced from ferromagnetic material, being formed on the fixed contact mount (18). It is proposed that the fixed contact mount (18) be formed with a holding opening (17) and that the switching arc guide apparatus (30) be in the form of an inlay element which can be mounted with a force fit in the holding opening (17) on the fixed contact mount (18).

A contact system for a pole of a low-voltage switchgear includes a rotary contact mounted movably in a rotor housing. The rotary contact includes at least a first rotary contact body having a first and second lever arm. Each of the lever arms include a lever arm end having a contact piece. A first and second fixed contact each cooperate with a respective one of the contact pieces. A first spring acts on the first lever arm and a second spring acts on the second lever arm. Each of the springs have a first support at a first end, a spring body and a second support at a second end. The first supports directly engage the first rotary body and the second supports are disposed at the rotary housing. Each of the spring bodies are disposed on a same side of the first rotary contact body.

A switch lock for an electrical switching device, e.g. a circuit breaker, motor circuit breaker, or isolating switch, which is an improved switch lock, that can be made with fewer parts and at lower cost. Furthermore, an electrical switching device can contain this switch lock. Due to an appropriate arrangement of the spring coupling points and an appropriate spring dimensioning, as well as an appropriate geometric design of the contact piece holder, this switch lock can do without separate lock and contact pressure springs, insofar as their functions are combined in one spring.
