Mechanical switching device

Abstract

The invention discloses a mechanical switch device. The mechanical switch device comprises a switch structure, a contact structure and a driving structure, wherein the switch structure comprises a current input end and a current output end which are disconnected, and the contact structure comprises a first contact and a second contact which are electrically connected; the current input end and the current output end respectively correspond to the first contact and the second contact; the contact structure can linearly move in the direction facing the switch structure or deviating from the switch structure under the action of the driving structure, so that the first contact and the second contact are in contact with the current input end and the current output end respectively, or the first contact and the second contact are disconnected with the current input end and the current output end respectively. According to the invention, the loop is small, the inductance of the switching loop can be reduced, the electromagnetic interference can be reduced, the stable output of the pulse waveform can be ensured, and the heating value can be reduced, so that the problems that the switching loop of the switching device in the related technology can generate large inductance, the pulse waveform is influenced, electromagnetic radiation interference can be generated, and a large amount of heat can be released are solved.
