The invention relates to an electrical switch (30) for an electrical appliance (2), in particular for a power tool, which has at least two switching contacts (34, 36), which can be jointly moved between a switched-off position (38), in which the switching contacts (34, 36) have no electrical connection to a counter contact (42) of the switch (30), and a switched-on position (40), in which the switching contacts (34, 36) are electrically connected to the counter contact (42). To maintain a contact resistance of the switch (30) at a largely constant value over the service life, it is proposed to arrange and/or design the switching contacts (34, 36) and/or the counter contact (42) such that, when the switch (30) transitions between the switched-off position (38) and the switched-on position (40), the switching contacts (34, 36) successively enter into electrical contact with the counter contact (42) or successively break the electrical contact.

A trigger switch that is used in electric devices such as various types of electric tools may be provided that drives a drive unit, such as a drive motor of the electric device, by pushing a trigger. A trigger switch includes a mode switching lever that switches between a constant speed mode in which the drive unit is driven at constant speed and a shift mode in which the drive unit is driven by an output corresponding to a pushing amount of a trigger. Further, the mode switching lever includes a regulating portion that regulates the pushing amount of the trigger according to the switched mode.

A battery pack is provided including a body having a first wall forming a first face from which a connection port extends for connection to a power tool or a charger, and a second wall forming a substantially planar second face. A finger notch recessed in the second face extends along an elongate axis perpendicular to a longitudinal axis of the body.

A fastening tool including a housing having a handle portion, a base for releasably mounting a power source, a nosepiece for driving fasteners into a workpiece, a magazine for feeding successive fasteners into the nosepiece, and a trigger. The trigger is configured to activate a trigger switch and initiate a fastener driving sequence. The trigger has a proximal end pivotably connected to a handle body and a distal free end adjacent to the base. The distal free end of the trigger has a curved body that extends substantially parallel to the magazine.

An actuation unit for a household appliance, preferably an electrically drivable, household appliance, includes an actuation element, having an actuation element base. The actuation element has a protrusion portion extending from the actuation element base, which is inserted into a recess of an actuation button, such that the actuation element and the actuation button have, in an assembled state, a degree of freedom in a direction corresponding to the extension of the protrusion portion and in a further direction.

The invention provides an electric drill including a bracket with a handle, a drill rod, a motor assembly, and a switch assembly. The switch assembly includes a first micro switch configured to activate or deactivate the motor assembly, a switch pivotably mounted on the handle through a pivot and cooperating with the first micro switch, and a self-locking button engaged with the switch and configured as: when the self-locking button is in a first state, the self-locking button abuts against the switch to prevent the switch from rotating around the pivot; when the self-locking button is in a second state, the self-locking button is disengaged with the switch, and the switch can rotate around the pivot.

An electrical switch including: a switch housing; a switch circuit disposed within the switch housing; said switch circuit including a movable contact member mounted on a contact lever and a stationary contact member; the contact lever being configured for operable-interaction with an actuator, said actuator being configured for movement along an actuator movement axis relative to the contact lever between at least one of an OFF position whereby the contact lever is configured for arrangement in to the first configuration whereby the switch circuit is opened, and, an ON position in which the contact lever is configured for arrangement in to the second configuration whereby the switch circuit is closed; a biasing element configured for biasing the contact lever towards the second configuration; so that the switch circuit is closed when the actuator is moved relative to the contact lever in to the ON positions, said biasing element including a first end attached to a first attachment point in connection with a portion of the contact lever and a second end attached to a second attachment point in connection with the switch housing; and an attachment member configured for attachment with the contact lever whereby when attached to the contact lever, said attachment member is configured for operation as the first attachment point in connection with the portion of the contact lever.

A childproof light switch cover apparatus for preventing a child from accessing a light switch includes a cover plate configured to engage a standard light switch box. The cover plate has a switch aperture extending therethrough that is dimensioned to receive a switch of the standard light switch box. A tubular extension is coupled to the cover plate around the switch aperture. A locking tab is coupled to a sidewall of the extension adjacent an outer threaded portion of the extension. A cap has a main portion and a flanged bottom portion. The cap is threadingly engageable with the outer threaded portion of the extension and the flanged bottom portion is selectively engageable with the locking tab to prevent the cap from rotating to disengage from the extension. The locking tab is substantially flexible to be depressed and to allow the cap to rotate freely.
