Moreover, accordingto some embodiments, the user interface module 5'may allow a user to activate a limited activated state via the buttons 37.
According to the illustrated embodiments, the user interface module 5' comprises a lightemitting device 39, in the form of a display 41, configured to output at least one operationalaspect of the power tool 20'. According to further embodiments, the user interface module 5'may comprise a light emitting device 39 in the form of a signalling lamp, or the like. The lightemitting device 39, and/or the display 41, of the user interface module 5' may output anactivation state of the power tool 20', a charge level of a battery of the power tool 20', a fuellevel in a fuel tank of the power tool 20', an activation state of an operational mode of thepower tool 20', a current power output of the power source 46 of the power tool 20', or thelike. The second type of user interface module 5' may comprise further electrical componentsthan indicated in Fig. 1b, such as one or more circuit boards, one or more control units, oneor more memory units, and the like. A control unit of the second type of user interfacemodule 5' may communicate with the control unit 35 of the power tool 20' via the electrical connection 33.
As understood from the above, since the first user interface arrangement 1 and the seconduser interface arrangement 1' comprises a holder 3 with the same layout and dimensions,the user interface module 5 of the first user interface arrangement 1 can be mounted into theholder 3 of the second user interface arrangement 1' and vice versa. As a result thereof, aset 30 of user interface arrangements 1, 1' is provided which provides conditions for reducingdevelopment costs, manufacturing costs, and assembling costs of power tools 20, 20'. Thisbecause a set 50 of power tools 20, 20' can be provided with different types of user interface modules 5, 5' without having to change major components of the power tools 20, 20', thus reducing development costs, manufacturing costs, and assembling costs of the power tools20, 20". lt is to be understood that the foregoing is illustrative of various example embodiments andthat the invention is defined only by the appended claims. A person skilled in the art willrealize that the example embodiments may be modified, and that different features of theexample embodiments may be combined to create embodiments other than those describedherein, without departing from the scope of the present invention, as defined by the appended claims.
As used herein, the term "comprising" or "comprises" is open-ended, and includes one ormore stated features, elements, steps, components, or functions but does not preclude thepresence or addition of one or more other features, elements, steps, components, functions or groups thereof.
