Abstract: The contact structure includes a first contact, a second contact, a first contact arm and a second contact arm. In an embodiment, the first contact arm includes at least two spring plates, arranged one on top of another and fixed at one end. The second contact is located on the second contact arm. The first contact is located on the spring plate, on a side of the first contact arm relatively closer to the second contact arm. The at least two spring plates, under a driving action, experience elastic deformation which causes the first contact and the second contact to come into contact with each other. The switch apparatus includes at least one driver and the contact structure of an embodiment. An embodiment of the present solution can reduce the number of contacts in a contact structure.
