This mechanism also provides long mechanical life. C High torque bushing construction prevents rotation or separation from frame during installation. Antijamming design protects contacts from damage due to excessive downward force on the actuator. Compatible companions with M series toggles. Body, bushing, and footprint dimensions ideal for mounting MB2400 pushbuttons and M toggles next to one another. Stainless steel frame resists corrosion. Longer center solder lug terminal simplifies wiring and soldering. Silver contacts of specially composed alloy for hardness. Epoxy sealed terminals prevent entry of solder flux and other contaminants. Prominent external insulating barriers increase insulation resistance and dielectric strength.
