Abstract:
The invention includes a device (15) designed to contain at least one button cell battery (6), where the device (15) includes at least one contact spring (7) with at least another contact surface (5a), designed to provide electrical contact to another conducting track (3) on a circuit board (1). The contact spring (7) also includes at least a first contact surface (4a) designed to provide electrical contact with the other battery terminal (6b). The first battery terminal (6a) and a first conducting track (2) on the circuit board (1 ) include a joint contact area. The device (15) includes at least one holder item (9) with first items, which first items are designed to fix the circuit board (1) and the device also includes other items, which other items are designed to fix the contact spring / the contact springs (7) in the holder item (9). With the invention it is achieved that it is thus possible to achieve a very compact product design since the batteries (6) are situated very close to the circuit board (1). Furthermore, the solution ensures easy mounting and easy access for changing the batteries (6) when the product is opened.
