Honeywell 4TL112 Military Toggle Switch

The TL series MICRO SWITCH™ toggle switch is a military-qualified, sealed toggle switch designed for demanding applications such as military, aerospace, industrial, and commercial uses. Constructed with high-quality materials, it features a bonded seal between the toggle lever and bushing, as well as between the cover and the case, ensuring durability in harsh environments. The robust design is suitable for environments subjected to mechanical shock, vibration, temperature extremes, dust, water splashing, or hose-directed water. These switches offer various circuitry options, including 1, 2, and 4-pole configurations, as well as 2- and 3-position, maintained, and momentary toggle actions. Locking levers help prevent unintended actuation. Termination options include screw, solder, and IWTS connections. Contact options are silver alloy or gold-plated to handle different electrical loads, suitable for low-voltage DC applications. The switch meets MIL-DTL-3950 and MIL-DTL-83731 standards for military-grade components. Its engineered step-design case provides extra space between terminals to prevent short circuits. Ideal for defense, military, aerospace, automation, process control, industrial, and commercial applications. Do not use these switches as safety or emergency stop devices, as failure could cause personal injury.
