MB2400-Series Miniature Pushbutton Switches3A Power Level & 0.4VA Logic Level; Snap-in, Bushing and PCB Mount, Snap-Action Mechanism, UL, CSA, cULusSnap-action Pushbutton SwitchesShort stroke and light touch. Internal o-ring protects against contamination. High torque bushing construction prevents rotation or separation from frame during installation. Anti-jamming design protects contacts from damage caused by excessive downward force on the actuator. Stainless-steel frame resists corrosion. Longer center solder lug terminal simplifies wiring and soldering. Patented silver contacts of specially composed alloy for hardness. Epoxy sealed terminals prevent entry of solder flux and other contaminants. Snap-acting mechanism gives smooth actuation and audible feedback. Prominent external insulating barriers increase insulation resistance and dielectric strength.
