摘要： An electromechanical switch includes a housing, first and second stationary contacts mounted to the housing, a movable contact, and a carrier sub-assembly. The housing has a divider wall. The carrier sub-assembly includes a support rod that extends through an aperture in the divider wall and is coupled to the movable contact. The carrier sub-assembly is configured to move the movable contact relative to the first and second stationary contacts. The carrier sub-assembly includes a contact spring surrounding the support rod between the divider wall and the movable contact. The carrier sub-assembly also includes a dampener in engagement with the contact spring. The dampener is configured to absorb vibration along one or more of the contact spring or the movable contact.

摘要： A contactor includes a housing having an outer wall defining a cavity, fixed contacts and a movable contact within the cavity, and a coil assembly in the cavity operated to move the movable contact between an unmated position and a mating position with the fixed contacts. The contactor includes an arc suppressor in the cavity including a first magnet located in the cavity on a first side of the movable contact and a second magnet located in the cavity on a second side of the movable contact. The first magnet is arranged in the cavity such that a north B-field of the first magnet faces outward toward the outer wall of the housing. The second magnet is arranged in the cavity such that a north B-field of the second magnet faces outward toward the outer wall of the housing.

摘要： Electromechanical switch includes first and second stationary contacts. Each of the first and second stationary contacts has a respective mating end. The electromechanical switch also includes a movable contact having first and second contact zones. The first and second contact zones are separate regions of the movable contact that are operable to be covered by the respective mating ends of the first and second stationary contacts, respectively. Each of the first and second contact zones has a mating surface and a corresponding recess that divides at least a portion of the mating surface. Each of the respective mating ends is configured to extend across the corresponding recess and engage the corresponding mating surface on opposite sides of the corresponding recess. The corresponding recess has a depth that extends only partially into the movable contact.

摘要： An electromechanical switch includes first and second stationary contacts and a movable contact. Each of the first and second stationary contacts has a respective protrusion at a mating end thereof. The movable contact defines a first depression and a second depression along a mating side thereof. The movable contact is reciprocally movable into and out of a closed position relative to the first and second stationary contacts. In the closed position, the mating side of the movable contact engages the mating ends of the first and second stationary contacts such that the protrusion of the first stationary contact projects into the first depression and the protrusion of the second stationary contact projects into the second depression.

摘要： 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.

摘要： A contactor includes an housing having a cavity, fixed contacts received in the cavity having mating ends in the cavity, a movable contact movable within the cavity between a mated position and an unmated position and engaging the fixed contacts to electrically connect the fixed contacts in the mated position, and a coil assembly in the cavity operated to move the movable contact between the unmated position and the mating position. The contactor includes an arc suppressor in the cavity. The arc suppressor includes a multi-pole magnet having a first magnet having a first pole and a second magnet having a second pole. The first magnet is integrated with the second magnet in a unitary magnet body.
