Abstract
The utility model provides a contact button switch and an electrical connection assembly, the contact button switch comprises a moving assembly and a button main body, and the button main body is provided with an installation cavity with an upper end and a lower end being open. The key main body is provided with a clamping piece and a first magnetic attraction piece; the moving assembly comprises a keycap partially arranged in the mounting cavity, a conductive piece arranged at the bottom of the keycap and located in the mounting cavity, and a second magnetic piece arranged on the keycap and located in the mounting cavity. The electrical connection assembly comprises the substrate and the contact key switch, the substrate is provided with the clamping hole, and the clamping piece is matched with the clamping hole to fix the contact key switch on the substrate, so that the complexity of welding is avoided. The substrate is provided with a plurality of disconnected wires below the corresponding conductive part, and the key cap is configured to move downwards under the action of external force to drive the conductive part to be arranged at the bottom of the key body to be in contact with the plurality of wires, so that the plurality of wires are electrically connected. And the first magnetic attraction piece and the second magnetic attraction piece attract each other, so that the service life can be prolonged, and the quality can be better controlled.
