A modular transfer switch () and actuator () wherein multiple transfer switches are connectable in linear arrangement with the actuator such that the actuator controls the position of all of the transfer switches. Each of the transfer switches () includes a contact assembly () that converts over-rotation of the drive linkage () in the transfer switch to added pressure between the load contacts and the power contacts in the contact assembly. The actuator has an embodiment wherein a joint () that connects counter-rotating arms () is linked to the armature of a linear motor () and spring tension from springs () is additive to the closing force applied to the transfer switches ().

An electrical switching device includes a switch housing and first and second circuit assemblies received in the switch housing. Each of the first and second circuit assemblies include a base terminal and a moveable terminal moveable between an open state and a closed state. The moveable terminal is electrically connected to the base terminal in the closed state. An actuator assembly is received in the switch housing. The actuator assembly includes a motor that has a drive coil generating a magnetic field. First and second pivots are arranged within the magnetic field of the drive coil. The first and second pivots are rotated when the drive coil is operated. First and second actuators are coupled to the first and second pivots and are slidable within the switch housing. The first and second actuators are operatively coupled to the moveable terminals of the first and second circuit assemblies, respectively. The first and second actuators move the moveable terminals between the open and closed states.

Electrical switching device

An electrical switching device includes first and second circuit assemblies. Each of the first and second circuit assemblies includes a base terminal and a moveable terminal movable between an open state and a closed state. The movable terminal is electrically connected to the base terminal in the closed state. An actuator assembly is electromechanically controlled by a motor. The actuator assembly includes a pivot member rotated by the motor that has a post extending outward from a pivot body. An actuator is moved by the pivot member and is movable between a first position and a second position. The actuator is operatively coupled to the moveable terminals of the first and second circuit assemblies. The actuator moves the movable terminals to the closed state as the actuator is moved from the first position to the second position. The actuator has a pocket with a compression spring received in the pocket. The compression spring extends between a first end and a second end. The first end engages the actuator. The second end engages the post. The compression spring provides a force on the actuator to push the movable terminals toward the base terminals.

An electrical switching device that includes first and second circuit assemblies. Each of the first and second circuit assemblies includes a base terminal and a moveable terminal that is configured to flex to and from the base terminal. The switching device also includes a coupling element that is operatively coupled to the moveable terminals of the first and second circuit assemblies. The switching device also includes an electromechanical motor that has a pivot body that is operatively coupled to the coupling element. The pivot body is configured to rotate bi-directionally about a center of rotation. The pivot body moves the coupling element side-to-side along a longitudinal axis so that the moveable terminals move in a common direction with respect to each other and along the longitudinal axis when the pivot body is rotated between first and second rotational positions.

Electrical switching devices having moveable terminals

The invention is directed to a switch assembly which can be used in situation in which the switch accommodates the flow of high voltage current. An actuator assembly with moveable contacts is moved by a motor driven armature. The moveable contacts are in electrical engagement with the stationary contacts when the armature is in the first position, and the moveable contacts are spaced from the stationary contacts when the armature is in the second position. By angling the stationary contacts and moveable contacts, the linear motion of the armature causes the moveable contacts to move across the surface of the stationary contacts as the armature approaches the first position. As all of the movements of the assembly are in a direction parallel to the axis of the armature, the assembly can be manufactured and operated reliably in a relatively small space. In addition, the linear movement on the angled contact provides for a positive electrical connection even in adverse environments.
