Product Description

Honeywell MICRO SWITCH TW Series toggle switches are qualified to MIL-83731 specifications for sealed and unsealed toggle switches. Quality construction features include an available bonded seal between the toggle lever and bushing for those applications where a sealing-related failure cannot be tolerated.
 

The durable design of the TW Series toggle is well-suited for many aerospace and other demanding applications where space behind the panel is limited. These applications include environments where the panels are subjected to mechanical shock, vibration, dust, splashing or hose-directed water, and temperature extremes.
 

MICRO SWITCH TW toggles feature a miniature MT-grade design with environmental sealing capabilities and can be configured with a large selection of circuitries, electrical 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 MT 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

 

FEATURES

• MIL-DTL-83731 qualified switches are available to meet MT/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)
