The difference is the switch labeling and orientation: the RK40820 is labeled Off-On (off is the first position), while the \u003ca href=\"\/products\/sierra-rk40800-compact-marine-rocker-switch-on-off-spst-12-24vdc-ac-rated\"\u003eSierra RK40800\u003c\/a\u003e is labeled On-Off. Choose based on which orientation matches your panel layout or labeling convention.
