Abstract: An electrical switch having a contact system including at least one fixed contact and a switching contact. The switch has an actuating element for acting in switching fashion on the contact system and a switching slide which bears the switching contact and is moveable in a movement direction between two positions, wherein in one position the switching contact is remote from the fixed contact and in the other position the switching contact bears against the fixed contact. The switch has an actuating slide which is moveable by virtue of the actuating element and is coupled to the switching slide by an elastic element. The switch includes a latching mechanism which interacts with the switching slide, such that the switching slide can be switched over between the two positions on actuation of the actuating element with a type of snap-action movement.

Abstract translation: 一种电开关，具有包括至少一个固定触点和开关触点的触点系统。 开关具有用于以接触系统的切换方式起作用的致动元件和承载开关触点的开关滑块，并且可在两个位置之间沿运动方向移动，其中在一个位置，开关触点远离固定触点，并且在 开关触点与固定触点相对的另一个位置。 开关具有致动滑动件，该致动滑块可由致动元件移动，并通过弹性元件联接到切换滑块。 开关包括与开关滑动件相互作用的闩锁机构，使得切换滑块可以通过一种快速动作运动在致动元件致动时在两个位置之间切换。

Abstract: A device for reversing the direction of rotation and/or for adjusting the carbon brushes for a reversible electric motor, in particular for an electric hand tool, with a base and with a mount, which is mounted pivotably on the base and on which brushholders for the carbon brushes wiping over the collector of the electric motor are arranged. The electric motor can be driven by means of power electronics, such as a pulse width controller, a phase gating controller, a phase chopping controller or the like. The power electronics are arranged on the base and/or on the mount. The device furthermore has fixed contacts and switching contacts, which interact with alternate contact-making for reversing the direction of rotation of the electric motor as the mount is pivoted.
