MICRO SWITCH Miniature Military-Grade Toggle Switch 005431 TW Series Issue 3 Datasheet FEATURES MIL-DTL-83731 qualified switches are available to meet military/aerospace specifications 1- and 2- pole options along with 2- and 3-position, maintained and momentary toggle action Wide temperature range: -65 C to 71 C -85 F to 160 F 1/4 in and 15/32 in bushing diameters Standard, locking, & colored paddle levers Optional lever locks (pull-to-unlock) require two separate actions to actuate Three popular termination options: screw, solder, and IWTS (Integrated Wire Termination System) Silver alloy or gold-plated contacts Electrical endurance of 20,000 cycles at full load DESCRIPTION Honeywell MICRO SWITCH TW Series toggle switches are POTENTIAL INDUSTRIAL APPLICATIONS military qualified to MIL-83731 specifications for sealed Military and commercial aircraft and helicopters and unsealed toggle switches. Quality construction features Aviation ground support equipment include an available bonded seal between the toggle lever and Military land vehicles (track and wheeled vehicles) bushing for those applications where a sealing-related failure Industrial machinery and construction equipment cannot be tolerated. Process control The durable design of the TW Series toggle is well-suited for many military, aerospace and other demanding applications DIFFERENTIATION where space behind the panel is limited. These applications Miniature size saves space and weight include environments where the panels are subjected to Variety of terminations, circuitries, and lever options for a mechanical shock, vibration, dust, splashing or hose-directed number of applications water, and temperature extremes. PORTFOLIO MICRO SWITCH TW toggles feature a miniature military- In addition the the TW Series, Honeywell offers six series of grade design with environmental sealing capabilities and can MICRO SWITCH toggle switches including the TL Series, NT be configured with a large selection of circuitries, electrical Series, TS Series, ET Series, and AT Series. terminations, lever and bushing designs, and contact material options to satisfy a diverse range of applications. VALUE TO CUSTOMERS MIL-DTL-83731 qualified switches available to meet military specifications Environmental sealing availability enables switches to withstand many demanding indoor and outdoor applications Miniature size (small footprint) for applications where behind-the-panel space is at a minimum 2- and 3-position, maintained and momentary toggle action to meet circuit and actuator requirements Sensing and Internet of ThingsMICRO SWITCH Miniature Military-Grade Toggle Switch, TW Series Table 1.
