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
