TE-21231, MS24656-231 The TE series is a MIL qualified, snap-action, non-teasible, positive make and break, panel mount toggle switch. The non-teasible mechanism assures that the switch will actuate and not “hang up” even when actuated very slowly. An O-ring seals the contact area from contaminants such as dust, moisture and sand. All metal components are corrosion resistant and designed to exceed all military requirements. This environmentally sealed switch is on-none-on double pole configurations with 1/4-40 bushings.
