Distinctive Characteristics
Antijamming design protects against mechanism damage from downward force
on the actuator.
O-ring surrounding top of lever prevents liquids from reaching
switch mechanism.
Ultrasonic welding of upper and lower housing seals out
contaminants and allows automatedsoldering and cleaning.
Terminals are epoxy sealed to prevent entry of flux,
solvents, and other contaminants.
Bracketed models have crimped bracket legs to ensure
secure PC mounting and prevent dislodging during
automated soldering.
Logic level and power capabilities are available to suit
varying applications.
