Miniature Slides
Series MS
Distinctive Characteristics
Bright, LED illumination at top of actuator.
Over-center actuator block and plunger design gives crisp
actuation, diminishes sparking, and increases operating life.
Guide interlocked with actuator block prevents
window locking and maintains correct plunger
alignment to assure contact stability.
Antijamming design protects contacts from
damage due to excessive downward force
on the actuator.
High internal barriers between poles and
insulating sheet between case and actuator
block give added protection to contacts.
Prominent external insulating barriers increase
insulation resistance and dielectric strength.
Epoxy sealed terminals prevent entry of flux, solvents,
and other contaminants.
Clinching of frame to case well above base and terminals provides
1,500V dielectric strength.

LED COLORS & SPECIFICATIONS
LEDs are supplied as an integral part
of the switch (not available separate-
ly). The lamp circuit is independent of
switch operation. Electrical specifica-
tions shown are determined at a basic
temperature of 25°C.
If the source voltage exceeds the rated
voltage, a ballast resistor is required.
The resistor value can be calculated
by using the formula given in the
Supplement.
