MICRO SWITCH TL Series
Toggle Switches
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 provides reliable performance with
long operating life under the toughest conditions.

VARIETY OF CIRCUITRIES AND OPERATING ACTIONS
TL Series’
1, 2, and 4 pole options
meet a variety of circuitry requirements; while
2- and 3-position, maintained and momentary
toggle action, for a breadth of
circuitry and actuator requirements. They thrive in a wide range of temperatures:
-65 °C to 71 °C [-85 °F to 160 °F]
Locking levers reduce unintended actuation
LOCKING LEVERS
Optional
lever locks
(pull-to-unlock) require two separate actions to actuate the
switch in order to prevent unintended actuation
MULTIPLE CONNECTION OPTIONS
MICRO SWITCH TL Series toggles offer
three popular termination options:
screw, solder lugs, and IWTS (Integrated Wire Termination Systems)
EASILY CONTROLS LOW-VOLTAGE DC APPLICATIONS
Toggle switches available with a choice of
silver alloy or gold-plated contacts
to handle a variety of electrical load requirements
INNOVATIVE PRODUCT DESIGN
Engineered step-design case provides added space between terminals to
prevent shorting
ROBUST CONSTRUCTION
Built from
military-grade components
to achieve MIL-DTL-3950 requirements
