A rocker switch assembly includes a switch body, a mounting strap, a frame, and a paddle for actuating the switch between an on and an off position. The paddle has a uni-convex cylindrical exterior surface. The rocker switch assembly further includes a faceplate in the form of a frame having an opening. The exterior front surface of the faceplate has a uni-convex cylindrical surface profile. In an assembled condition, the paddle substantially occupies the faceplate opening. Due to the selected convex shapes of the paddle and faceplate, a portion of the paddle front surface is always substantially flush with a portion of the faceplate surface and at no time does any part of the paddle surface protrude past the faceplate front surface.
