A method, a device (110) and an insulin pump (112) are disclosed. The method for connecting a force sensor (122) to a circuit board (114) of an insulin pump (112) comprises step a): providing the circuit board (114), comprising at least one first conductive lead (116) and at least one second conductive lead (118), wherein the first conductive lead (116) and the second conductive lead (118) are located on the same surface (120) of the circuit board (114). The method further comprises step b) providing the force sensor (122) having at least one flexible first contact tab (124) and at least one flexible second contact tab (126), wherein each contact tab (124, 126) comprises a contact pad (128), wherein the contact pad (128) of the first contact tab (124) and the contact pad (128) of the second contact tab (126) are arranged on opposite sides relative to each other. The method further comprises step c) arranging the first contact tab (124) such that the contact pad (128) of the first contact tab (124) faces the first conductive lead (116) of the circuit board (114). Further, the method comprises step d) arranging a first conductive rubber element (130) such that an electrical connection between the contact pad (128) of the first contact tab (124) and the first conductive lead (116) is established. The method further comprises step e) arranging the second contact tab (126) such that the contact pad (128) of the second contact tab (126) and the second conductive lead (118) face in the same direction, and further the method comprises step f) arranging a second conductive rubber element (132) such that an electrical connection between the contact pad (128) of the second contact tab (126) and the second conductive lead (118) is established.
