A power switching device, an electric energy storage system and an electric tool system are provided. The power switching device includes a plug connected to a power supply device and including an output terminal; and a power switching assembly connected to the plug and including a power switching member, the switching member is used for switching a coupling form of the plug. The power switching assembly further includes a control member for controlling the power switching assembly to move between different switching positions. The control member includes a switching button, and the switching position of the power switching assembly is switched by pressing the switching button.

A bistable device including a fixed baseplate, at least two levers, a tappet rigidly secured to between each lever and the baseplate and aligned in a first direction, where a lever is capable of displacement relative to the baseplate so as to displace the associated tappet substantially in translation in the first direction, and a member that is able to take two positions, the device additionally including a rocker associated with each lever, arranged between the baseplate and the associated tappet, including two V-shapes facing the associated tappet, where the associated tappet in the first V-shape tends to turn the associated rocker in a first direction and the associated tappet in the second V-shape tends to turn the associated rocker in a second direction opposite to the first direction, the rockers being synchronized in rotation and the rockers being synchronized with the member.

A switch having a push panel, a rocker, and a rocker actuator that actuates the rocker each time the push panel is pushed by a user. The switch includes a conductive switch member, that is toggled by the rocker, to connect and disconnect a first terminal from a second terminal. The switch is constructed to help reduce dust and debris from entering into the wall switch, and the switch may provide a visual cue to indicate a current ON/OFF state of the switch.

The electric switch comprises at least one key (4) that pivots about a pivoting axis (5) and a base (2) provided with at least one electric connection and disconnection actuation point (3), so that the pivoting of the key 4 causes the application of pressure to at least one actuation point 3 and causes the electric connection or disconnection, and it is characterized in that the base (2) comprises at least one pivoting actuator (6). A low-cost mechanical type electric switch is obtained which automatically returns to its rest position, and which for the user has the same sensation as an electronic type electric switch.

Electrical mechanism, which has an axial axis in which are arranged: a rocking lever configured to adopt a first position and a second position of electrical connection or disconnection; a striker configured to engage with the rocking lever in the first position and in the second position (P.sub.2); an actuating device configured to transmit an actuation force to the striker so that the striker engages with the rocking lever and changes the position thereof; and a spring configured to disengage the striker from the rocking lever once the actuation force is released. Two contact points for transmitting the actuation force are established between the striker and the actuating device of the electrical mechanism.

The invention relates to a bistable device which comprises a fixed baseplate (1), at least two levers (2a, 2b), a tappet (3a, 3b) which is associated with each lever (2a, 2b), is rigidly secured to the lever (2a, 2b) in question, is arranged between the lever (2a, 2b) and the baseplate (1), and is aligned substantially in a first direction (T1), wherein a lever (2a, 2b) is capable of displacement relative to the baseplate (1) so as to displace the associated tappet (3a, 3b) substantially in translation in the first direction (T1), and a member (5) that is able to take two positions, said device additionally comprising a rocker (4a, 4b) which is associated with each lever (2a, 2b), is arranged between the baseplate (1) and the associated tappet (3a, 3b), and comprises two V-shapes which face the associated tappet (3a, 3b), wherein a touch of the associated tappet (3a, 3b) in the first V-shape tends to turn the associated rocker (4a, 4b) in a first direction (R1+) and a touch of the associated tappet (3a, 3b) in the second V-shape tends to turn the associated rocker (4a, 4b) in a second direction (R1) opposite to the first direction (R1+), all the rockers (4a, 4b) being synchronised in rotation and said rockers (4a, 4b) being synchronised with the member (5).
