Datasheet
FEATURES
• Most ET switches are designed and qualified to SAE AS55941
military standards to meet the required military or commercial
aircraft requirements
• Uniquely designed with an integral solenoid which provides
electrically maintained switch contacts (magnetic latching) for
circuit requirements
• The solenoid can be over-ridden with manual movement of the
toggle lever where immediate release is required
• Four different styles of lever actuators and three different types
of electrical termination
• Temperature range of -65 °C to 71 °C [-85 °F to 160 °F] to
accommodate applications in controlled and uncontrolled
temperature environments
DESCRIPTION
• Catalog listings available with up to four poles for control of
multiple circuits or providing redundant circuit capability
MICRO SWITCH™ ET Series toggle switches are a specialty
type of toggle switch with an electrical latching mechanism. The
latching mechanism (internal solenoid in the switch) is designed
to hold the momentary switch contacts closed once the toggle
switch has been manually actuated. An auxiliary set or remote
set of contacts opens the solenoid circuit of the switch and
releases the toggle lever mechanism while opening the switch
contacts which were held closed.
POTENTIAL APPLICATIONS
• Flight decks for commercial and military aircraft
• Flight decks for commercial and military helicopters
PORTFOLIO
In addition the the ET Series, Honeywell offers six series of

To fulfill a variety of applications, the ET toggle switches are
available with up to four poles, with two or three toggle lever
positions, with or without lever locks. Most ET Series toggle
switches mount in the popular size 15/32 inch diameter hole. ET
toggle switches are designed to the military standards of SAE
AS55941 with many of the switches being military qualified.
VALUE TO CUSTOMERS
