Abstract: Skateboard trucks and skateboards using the improved trucks are disclosed. Truck according to the present invention can comprising a hanger with wheels. A base assembly is included having an at least partially hollow housing section. The hanger is rotationally mounted to the base assembly. The hanger also comprises a hanger portion that is within partially hollow housing section. Compressible spring elements are included within the partially hollow housing section, wherein the hanger portion operates on the compressible spring elements when the hanger rotates in relation to the base assembly. Skateboards are also disclosed that utilize the truck. One or more trucks are mounted to the skateboard deck with the truck having internal compressible spring elements that are compressed when turning the skateboard. The internal compressible spring elements also expand to return the truck to a neutral position when the skateboard is not turning.

Abstract: Described herein are contactors comprising one or more split or otherwise sectionalized contacts. By comprising split contacts, contactors incorporating features of the present invention increase the number of electrical contact sites between the split contactor and another contactor, allowing current to flow through multiple sites and preventing or mitigating the formation of magnetic fields, harmonic resonance and resulting vibration and noise production. In some embodiments, the contactors comprise at least one bifurcated (split in two) moveable contact and at least one fixed contact. The bifurcated contact can be configured such that it can be easily manipulated as if it were a singular contact, while simultaneously providing the advantages of a bifurcated one.
