DESCRIPTION
Honeywell MICRO SWITCH TL Series toggle switches are
military qualified to MILDTL3950, specifications for sealed
toggle switches. Quality construction features include a
bonded seal between the toggle lever and bushing, and
between the cover and case.
The robust design of the TL Series toggle is well-suited for
many military, aerospace and other demanding applications
where reliability is essential. These applications include
environments where the panels are subjected to mechanical
shock, vibration, and temperature extremes as well as
environments with dust, splashing or hose-directed water.
TL Series toggle switches offer a variety of circuitry and pole
options to easily integrate into a number of applications.
A long history in military and aerospace applications
has shown the TL Series toggle switches provide reliable
performance with long operating life under the toughest
conditions.
