Miniature T3 Commercial & MIL-Grade Toggles

OTTO Miniature T3 Commercial- and Military-Grade Toggles are rugged, highly reliable switches offering positive detent action for safe switching operation. These OTTO devices feature snap-action switch actuation with a unique toggle actuator design. High contact pressure and superior wiping action make the T3 series an excellent choice for switching loads from logic level up to 5A. Choose sealed one- or two-pole circuitry and momentary and/or maintained operation. The 15/32-32 bushing model is also available with a lever lockout toggle feature or thumb button actuators.
