The invention relates to a double-rocker wall switch comprising a panel, a first switch assembly and a second switch assembly. The first switch assembly comprises a first rocker, and the second switch assembly comprises a second rocker. The double-rocker wall switch further comprises a first sealing member which can deform under force, a first pressure box, a second pressure box, and a third pressure box. The first sealing member shaped like the Chinese character 'Ri' comprises a ring body and a cross rib, and the cross rib divides the hollow part of the ring body into a first grid and a second grid. The outer sides of the ring body of the first sealing member are clamped between the third pressure box and a panel flange, the sides forming the first grid are clamped between the first pressure box and a first rocker flange, and the sides forming the second grid are clamped between the second pressure box and a second rocker flange. The double-rocker wall switch is waterproof and dustproof. By designing the first sealing member, and especially by adding the cross rib, the space left between the first rocker and the second rocker can be blocked effectively.
