The link member is capable of pressing the contact piece. The link member includes a first pressing portion and a second pressing portion. The first pressing portion is configured to press the first divided piece, and extends in a widthwise direction of the contact piece. The second pressing portion is configured to press the second divided piece, and extends in a lengthwise direction.

A personal vaporizer mod device includes a switch having a switch button member that carries a first magnet of first polarity. A switch insulator is secured within a switch body and has a central orifice and an internal counterbore section, which receives a switch firing pin and a second magnet having a polarity opposite the first magnet. The switch button member is repelled such that no contact exists between the switch firing pin and switch button member, but when depressed, the switch button member establishes electrical contact and current flows via a battery received within a mod housing to coils of the mod device.

A switch includes a first fixed contact, a second fixed contact, a movable contact, a drive shaft, a first outside yoke, a second outside yoke, a first inside yoke, a second inside yoke, and a permanent magnet. The permanent magnet magnetically couples the first outside yoke, the second outside yoke, the first inside yoke, and the second inside yoke, and produces a magnetic field component in a direction in which the first fixed contact point and the second fixed contact point are aligned, between the first fixed contact point and the first movable contact point and between the second fixed contact point and the second movable contact point.

An electrical switch for an electric machine includes body, a stator fixedly secured to the body and a rotor. The actuator includes a first member securable to the rotor and rotatable with it. The actuator also includes a second member, a first electrically conductive member cooperates with the second member. The actuator also includes a second electrically conductive member. The second electrically conductive member is spaced from said first electrically conductive member when said first electrically conductive member is in the first axial position and electrically engaged with said first electrically conductive member when said first electrically conductive member is in the second axial position.

A switch can be used for an on-load tap changer. The switch includes: fixed contacts, including a first fixed contact and a second fixed contact; and a moving contact with a first attraction element. The moving contact is movable from a first position into a second position via the first attraction element and a second attraction element, which is arranged outside the switch. The moving contact is configured such that, in the first position, the moving contact contacts neither or only one of the fixed contacts and, in the second position, the moving contact contacts both of the fixed contacts.

The disclosure provides a hydraulic switch including a casing, a first cable, a second cable, an electrically conductive piston and a first magnetic conductive component. The casing has a chamber and a liquid channel connected to the chamber. The first cable is disposed through the casing, and the first electrical connection portion of that is located in the chamber. The second cable is disposed through the casing, and a second electrical connection portion of that is located in the chamber. The electrically conductive piston movably is disposed in the chamber. When the electrically conductive piston is in an electrically connected position, the electrically conductive piston is in electrical contact with the first electrical connection portion and the second electrical connection portion. The first magnetic conductive component is configured to provide a magnetic force to move the electrically conductive piston toward an electrically disconnected position.

A power system is disclosed. The system may include an electrical contactor including a pair of plates arranged to scissor between open and closed positions. The plates may have magnets embedded therein such that in the closed position, a subset of the magnets having opposite polarity are aligned to encourage touching of electrical contacts of the plates, and in the open position, a subset of the magnets having same polarity are aligned to encourage separation of the electrical contacts.

A modular transfer switch (22) and actuator (20) 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 (22) includes a contact assembly (48) that converts over-rotation of the drive linkage (26) 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 (400) that connects counter-rotating arms (396,398) is linked to the armature of a linear motor (507) and spring tension from springs (423, 424) is additive to the closing force applied to the transfer switches (22).

The link member is capable of pressing the contact piece. The link member includes a first pressing portion and a second pressing portion. The first pressing portion is configured to press the first divided piece, and extends in a widthwise direction of the contact piece. The second pressing portion is configured to press the second divided piece, and extends in a lengthwise direction.
