EXPLANATIONS OF SWITCHES WITH
SPECIAL REQUIREMENTS
High velocity actuation
This switch is designed to withstand near
‘‘hammer-blow’’ actuation as is found in
over-center locking mechanisms. It is di-
mensionally interchangeable with stan-
dard listing 1EN1-6.
Low force operation
Special spring construction within this
switch reduces the normal 6 to 12 pound
(26,7 to 53,4 N) EN operating force to 3 to
6 pounds (13,3 to 26,7 N). This switch is
also dimensionally interchangeable with
the standard size 1EN1-6. Low force 600
series ENs have 3 to 6 pounds (13,3 to
26,7 N) of operating force.

Increased overtravel
A longer plunger and bushing on the
switch extends the EN overtravel capabil-
ities from the normal .250 inch to .860
(6,35 to 21,8 mm). The longer bushing al-
so permits additional adjustment of the
plunger position.
High impact shock
Catalog listing 1EN75-R3 (M8805/65-001)
has been qualified to MIL-S-8805, includ-
ing high impact shock class H. Other
switches rated for high impact shock ap-
plications incorporate the same plunger
mechanism and internal switch design as
used in the 1EN75-R3 and are expected to
conform to the same requirements.
