DESCRIPTION
The S Series product group
expands Eaton’s snap action
switch portfolio to cover all major
amperages and operating forces.
A wide range of sizes and options
gives customers the ability to
select the most appropriate switch
for their specific application.
Typical applications include
computers, consumer electronics,
small appliances, power tools,
vending machines and
packaging machinery.
Ultraminiature
The SC Series offers the smallest
size with ratings of 0.1A and 3A.
A choice of operating forces,
terminations and lever
combinations is available.
Subminiature
Slightly larger than the SC Series,
the SE/SEV Series offers more
options in operating force,
termination, and lever style. This
series also offers a 1PDT circuit
and a 1PST circuit with either NO
or NC terminals. The SEV version
has VDE microgap approval.
Subminiature Waterproof
The SF Series is ideal for
applications where the switch is
subject to submergence of water
or poor environmental conditions.
It has one current rating and
operating force but a variety of
terminations and lever
combinations. A 1PDT circuit and
a 1PST circuit with either NO or
NC terminals is available.
General
The SG Series is the standard size
snap switch with amperages from
0.1A to 15A, and a variety of
operating forces.
With VDE approval, the SGV Series
has a contact distance of larger
than 3mm.
Low Torque
The SJ Series is the low torque
series designed to meet
applications where a light
actuating force is needed.
A selection of operating forces and
lever combinations is available.
SPECIFICATIONS
See specification table.
Approvals:
Q SEV and SGV series only.
