[0001] The invention relates to the technical field of power switches, and in particular to a switch panel for avoiding poor contact. Background Art

[0002] The power switch is a commonly used electrical component in life, which controls the switch of electrical appliances or lamps. However, in the existing technology, when the button drives the conductive sheet to move, the spring on the conductive sheet is installed in the conductive installation groove, and no corresponding limit structure is set. In addition, there is space for the spring to move between the spring and the conductive installation groove, so that the spring cannot move accurately with the button, which easily causes incomplete contact between the conductive sheet and the conductive sheet, and then poor contact between the conductive sheet and the conductive sheet occurs, so that the switch cannot normally control the switch of the electrical appliance or lamp. For this reason, a switch panel that can improve the conduction effect between the conductive sheet and the conductive sheet and avoid poor contact is proposed. Summary of the invention

[0011] Preferably, both the conducting sheet and the conductive sheet are provided with flat contacts for facilitating conduction.

[0012] Preferably, the base is also provided with a conductive mounting groove for facilitating the installation of the spring.
