    Abstract: A MULTIPLE CONTACT ELECTROMAGNETICALLY OPERATED SWITCH HAVING A HOUSING THAT PROVIDES AN ENCLOSURE FOR THE ELECTROMAGNET OPERATOR OF THE SWITCH. THE HOUSING INCLUDES AT LEAST ONE METAL PART THAT HAS A HIGH COEFFICIENT OF THERMAL CONDUCTIVITY SO THE HOUSING ACTS AS A HEAT SINK AND A RADIATOR FOR HEAT GENERATED WITHIN THE ELECTROMAGNET WHEN A MAGNET COIL OF THE ELECTROMAGNET IS ENERGIZED. THE HEAT SINKING CAPABILITY IS ACCOMPLISHED BY RESILIENTLY SUPPORTING A PORTION OF A MAGNET CORE FOR THE ELECTRO-

    MAGNET ON THE METAL HOUSING PART IN A MANNER WHICH WILL PERMIT THE MAGNET CORE TO MOVE TOWARD THE ARMATURE PORTION OF THE ELECTROMAGNET WHILE THE ARMATURE IS MOVING TOWARD THE MAGNET CORE TO REDUCE THE IMPACT SHOCK WHICH OCCURS WHEN THE ARMATURE ENGAGE THE MAGNET CORE.

    Abstract: A movable contact structure having a movable contact member carried on a movable contact carrier by a spring biased rotatable plunger. The contact member has a channellike cross section and is formed of at least two laminated metals each having different deflection and conductive characteristics so that the weight of the contact member may be reduced and provide a maximum conductive ability commensurate with its resistance to bending. An end of the plunger extends through a notched opening in the contact member so that when the plunger is rotated to one position the contact member may be separated from the carrier and when the plunger is rotated to a second position, a pin on the end of the plunger engages the material of the contact member to maintain the contact member on the end of the plunger. The plunger also includes a portion that acts as a piston in a bore of the contact carrier to reduce the bounce which occurs when the movable contact surfaces on the contact member initially engage the stationary contacts.

    Abstract: THE CONSTRUCTIONAL DETAILS AND THE ARRANGEMENT OF THE COMPONENTS OF A MULTIPLE CONTACT ELECTROMAGNETICALLY ACTUATED SWITCH THAT HAS A CONTACT CARRYING PORTION OF A U-SHAPED MOVABLE CONTACT CARRIER MOVABLE IN AN EXTERNALLY EXPOSED SLOT IN A REAR WALL OF A BASE WHICH CARRIES THE STATIONARY CONTACTS. THE CONTACT CARRIER IS ACTUATED BY AN ELECTROMAGNET STRUCTURE THAT HAS THE STATIONARY MAGNET PART RESILIENTLY SUPPORTED ON A METAL HOUSING IN A MANNER SO THE STATIONARY MAGNET MOVES TOWARD THE ARMATURE TO MINIMIZE THE SHOCK AND THE BOUNCE BETWEEN THE CONTACTS OF THE SWITCH AND PERMIT THE METAL HOUSING TO ACT AS A HEAT SINK FOR THE HEAT ENERGY GENERATED WITHIN THE MAGNET WHEN THE ELECTROMAGNET IS ENERGIZED. THE COMPONENTS OF THE SWITCH ARE ARRANGED SO THAT THE SWITCH CAN BE READILY ASSEMBLED AND THE CONTACTS R THE ELECTROMAGNET CAN BE INDIVIDUALLY SERVICED WITH THE CONTACTS BEING READILY ACCESSIBLE IN EVENT THE MOVABLE CONTACTS ARE WELDED TO THE STATIONARY CONTACTS.

    Abstract translation: 一种可动接触结构，其具有通过弹簧偏置的可旋转柱塞承载在可动接触载体上的可动接触构件。 接触构件具有通道状横截面，并且由至少两个层压金属形成，每个层叠金属具有不同的偏转和导电特性，使得可以减小接触构件的重量并提供与其抗弯曲性相当的最大导电能力。 柱塞的端部延伸穿过接触构件中的切口开口，使得当柱塞旋转到一个位置时，接触构件可以与载体分离，并且当柱塞旋转到第二位置时， 柱塞接合接触构件的材料以将接触构件保持在柱塞的端部上。 柱塞还包括在接触载体的孔中用作活塞的部分，以减少当接触构件上的可动接触表面最初接合固定触点时发生的反弹。
