Military Purpose Toggle Switches
TOGGLE SWITCHES
2
DESCRIPTION
Eaton’s Military Purpose switches
are designed to meet the
requirements of MIL-S-83731 or
JAN-S-23. Sealed Switches have
a silicone rubber lever seal
assembled between the lever and
the bushing to resist the entrance
of contaminants such as dust,
sand or water into the
contact structure.
The switch mechanisms are
completely enclosed to resist the
entrance of contaminants into the
switch. All metal parts are plated
to resist corrosion. The Heavy
Duty Switches are offered in both
Standard Toggle Lever and Lever
Lock versions. Circuit
designations are stamped on the
side of each switch.
