发明名称 RESISTANCE DEVICE FOR HIGH VOLTAGE SWITCH ASSEMBLY
摘要 A resistance device for an electrical switch assembly includes a housing having a base and first and second support brackets extending outwardly therefrom. The base receives first and second conductive blades of the electrical switch assembly. A cam member is movably connected to the first and second supporting brackets. First and second spring members are connected between the base and the cam member and bias the cam member away from the base. The amount of force required to open and close the switch assembly is increased by having to overcome the resistance force imparted by the first and second spring members on the cam member during rotation of the conductive blades.
