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.

A lock member includes a fit portion, an inclined portion and a contacting portion. The fit portion is fitted with a projecting portion of a trigger to maintain an off-lock state. The inclined portion is brought into contact with a shaft of an unlock button and moves the lock member to release the off-lock state. The projecting portion is slidable on the contacting portion and maintains an on state.

A portable electronic device including a housing; a button hole formed in the housing; and a button unit arranged in the button hole of the housing is provided. The button unit includes a top button coupled to the housing and covering the button hole, with a first direction length larger than a second direction length; a button frame provided in the housing, with one portion in the second direction coupled to a bottom of the top button and the other portion in the second direction coupled to an internal space of the housing; an actuator projected from a bottom surface of the button frame; and a dome switch pressed by the actuator and generating a signal, when the top button is pressed.

A machine tool includes at least one handle housing having at least one switching unit with at least one ratchet element arranged on the at least one handle housing and at least one bearing unit, which is provided to support the at least one ratchet element at least movably relative to the at least one handle housing. The at least one bearing unit includes at least one lever drive unit, which is provided in order to enable a uniform stroke motion over an entire operating surface of the at least one ratchet element during an actuation of the at least one ratchet element.

An actuator is allowed to move toward +A direction and toward −A direction. A movable contact engages with the actuator. A fixed contact touch the movable contact with electrical connection when the movable contact is located at an ON position, and are apart from the movable contact with electrical isolation when the movable contact is located at positions other than the ON position. An arc prevention mechanism prevents arc between the movable contact and the fixed contact.

A switch mechanism (12) includes a housing (16, 18) with a fenestration (21), a switch element (22) held in the housing, and a membrane switch held in the fenestration. The membrane switch includes a flexible membrane (20) and a rigid rib (26). The rib is constrained to linear movement by guides (37, 38) in the housing so that contact with the membrane causes the membrane to deform and the rib to translate to actuate the switch element.
