TOGGLE SWITCHES
FEATURING OTTO’S UNIQUE SNAP-ACTION MECHANISM
These miniature toggles are rugged, highly reliable switches offering
positive detent action for safe switching operation. Featuring the
unique OTTO snap-action switch mechanism in conjunction with a
unique toggle actuator design, the T3 series offers non-teasible
contact transfer.
High contact pressure and superior wiping action of the OTTO design
makes the T3 series an excellent choice for switching loads from
logic level up to 5 amperes.
Choose sealed one or two-pole circuitry, 15/32-32 sealed or 1/4-40
unsealed bushing construction, momentary and/or maintained
operation. The 15/32-32 bushing model is also available with lever
lockout toggle feature or thumb button actuators.
Molded-in terminals seal the contacts against moisture and solder
flux wicking. The front-panel side of 15/32-32 bushing models are
sealed against water and other liquids per MIL-S-83731.
In addition to the single turret solder terminal specified in MIL-S-83731,
we also offer two different lengths of pins for printed circuit soldering.
Mounting hardware provided includes two hex nuts, one lockwasher
and one keyway washer.
Exclusive Quality Features:
• Non-teasible snap-action contact actuation
• Shorter behind panel depth
• Superior wiping action keeps contacts clean
• Positive tactile response prevents operating errors
• Weighs up to 25% less than competitive products
• More contact/terminal plating choices
• Highly reliable: simpler design, less parts
