Single unit construction of the bushing and top of the housing gives protection from cleaning fluids or other 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.
