Miniature Pushbuttons Series MB2000 Distinctive Characteristics Guide interlocked with actuator block prevents window locking and maintains correct plunger alignment to assure contact stability. Employs an over-center actuator mechanism, which diminishes sparking and increases operating life in AC circuits. High torque bushing construction prevents rotation or separation from frame during installation. Splashproof option (D3 and B3 bushing codes) features an o-ring within the bushing and one under the face nut to protect from splashed, sprayed, or spilled liquids. High insulating barriers, formed in the molded diallyl phthalate case, increase isolation of circuits in multipole devices. Prominent external insulating barriers increase insulation resistance and dielectric strength. Epoxy sealed terminals prevent entry of solder flux and other contaminants. Clinching of the frame to the case well above the base and terminals provides 1,500V dielectric strength.
