A voltage tap for measuring a voltage includes at least one contact region and one abutment surface. Using the abutment surface, the voltage tap is electrically connectable to a contact surface of an electrical circuit board. The abutment surface comprises an enlarged surface with respect to the contact surface of the electrical circuit board, so that the electrical connection between the voltage tap and the electrical circuit board is provided independently of a movement of the voltage tap.

A channel for cooling at least one battery cell is set out. The channel includes a first housing frame and a second housing frame. The first housing frame is connected to the second housing frame and a partially fluid-tight region is formed between the first housing frameand the second housing frame by the shape and material properties of the first housing frame and the second housing frame. The partially fluid-tight region forms the channel and the channel is arranged to allow a coolant to flow through the channel.

An operating control, in particular in a motor vehicle, wherein the operating control has at least one actuating element for actuating the operating control. The operating control comprises at least one sensor element operatively connected to the actuating element for registering an actuation, and at least one oscillator coil fixedly connected to the actuating element for emitting a mechanical feedback signal, in particular bending waves, through the actuating element. The feedback signal is haptically and/or acoustically perceivable, preferably simultaneously haptically and acoustically perceivable. The operating control includes a controller element for activating the oscillator coil in case of actuation of the operating control.
