An electric switch is provided. The electric switch comprises a contact system, an actuation element, an engaging latch, and an actuator. The actuation element moves between an initial position and an actuation position to switch and changeover the contact system. The actuation element is located in a direction of the initial position by a force of a return spring. The engaging latch locks the actuation element in the initial position or the actuation position. A non-manual unlocking between the actuation element and the engaging latch is performed by the actuator.

Provided according to the present invention is a solenoid with a built-in permanent magnet, with which it is possible to suppress an increase in the amount of magnetic flux that passes through the chuck part, even when the magnetic flux generated by a coil is greater than the magnetic flux of the magnet, and to reliably reduce attraction force. In this solenoid, a permanent magnet and a coil are both built into a cylindrical case having an opening part; the permanent magnet and the coil are both separated and arranged inside the case; a ring member is arranged adjacent to the permanent magnet; a movable iron core is inserted inside the coil; and between the movable iron core and the coil, a metal coil cover is provided so as to cover the coil. The distance d between the case inner wall and the ring member can also be in the range of 0.1-0.3 mm.

An electromagnetic actuating device includes an armature, which has a permanent magnet and can move along a longitudinal axis between actuation positions relative to a stationary coil and in reaction to energization, armature has an engagement section for interacting with a plunger, and which armature can move from a first actuation position, which is stable in the currentless state, into a second actuation position against a restoring force of a spring, wherein the coil has a first coil unit, which acts on the armature and which releases the armature from the first actuation position, wherein the coil has a second coil unit which, during movement, applies to the armature a force which accelerates the armature, and wherein the coil has a restoring coil such that when the armature is returned from the second into the first actuation position, the restoring coil boosts the restoring force of the spring.

A magnetic spring assembly that uses the bistable magnetic nature of permanent magnets mediated by a spring material to allow one or more attached vibrating masses to take on the damping characteristics of the magnetic spring assembly includes a permanent magnet body with an attach point 15 for a first vibrating mass, two spring materials, and two magnetic disks firmly attached to a shaft having an attach point 23 for a second vibrating mass to manufacture a mass damper 20 for damping vibrations on at least one of the attached masses. The spring materials can be an elastic material or a spring that is placed between the magnetic disks and the magnetic body to allow the magnetic disks to vibrate in a spring like manner. Passive tuning of the damping characteristics of the magnetic spring assembly is achievable through selected force tuning between the magnetic force from the permanent magnet and the compression force of the spring materials, and active tuning of the magnetic spring assembly is achievable by adding control coils in the magnet body to alter the magnetic force or having spring materials with characteristics that are electrically control to alter the compression force.
