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.
