Product Description

Honeywell MICRO SWITCH TW Series toggle switches are military 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 military, 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 military-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.
