Process Sealed Miniature Toggles
Series M2
Distinctive Characteristics
Antijamming actuator design protects against mechanism damage from
downward force on the toggle.
Single unit construction of the bushing and top of the housing
gives protection from cleaning fluids orother liquids.
O-ring surrounding actuator at top of bushing interior
prevents liquids from reaching switch mechanism.
Ultrasonic welding of upper and lower housing
seals out contaminants and allows automated
soldering and cleaning.
Terminals are epoxy sealed to prevent entry of
flux, solvents, and other contaminants.
Bracketed models have crimped legs to ensure
secure PC mounting and prevent dislodging
during automated soldering.
Logic level and power capabilities are available to suit
varying applications.
