A method for connecting a force sensor to a circuit board is disclosed. A circuit board having first and second conductive leads located on the same surface of the circuit board is provided. Also provided is a force sensor with a first flexible contact tab having a first contact pad and a second flexible contact tab having a second contact pad. The first contact pad is arranged to face the first conductive lead. A first conductive rubber element establishes an electrical connection between the first contact pad and the first conductive lead, and the second contact pad and the second conductive lead are arranged to face in the same direction. A second conductive rubber element establishes an electrical connection between the second contact pad and the second conductive lead. Also disclosed are an associated device for determining fluid pressure in an insulin pump and an insulin pump.
