An electrical assembly adapted for switching power to a circuit having a power source. The electrical assembly includes a housing with current carrying contacts disposed in the housing. The current carrying contacts have engagement ends with non-linear surfaces. A coupling member is provided in the housing. The coupling member has mating portions for engaging the non-linear surfaces of the current carrying contacts. The mating portions have grooves provided thereon which extend from top surfaces of the mating portions toward bottom surfaces of the mating portions. As the electrical assembly is moved to a closed position, the grooves of the mating portions of the coupling member are moved into engagement with the non-linear surfaces of the contacts, resulting in multiple contact points being provided between the non-linear surfaces of each respective contact of the current carrying contacts and edges each respective groove of the groove of the mating portions.
