When the cam moves to a first position, the rotor may rotate such that a lower surface of the cam engages with an upper surface of the rotor, and when the cam moves to a second position, the rotor may continue to rotate such that the upper surface of the rotor engages with a lower surface of at least one of the plurality of protruding blocks of the housing.

What is presented is a key module (100) comprising an actuation element (105) comprising a cam nose (135), wherein the actuation element (105) is supported to be movable along a movement axis (200) in a housing element (130, 110). Furthermore, the key module (100) comprises a contactor unit (115) with a contact nose (140) movable in the direction of the movement axis (200) and transverse to the direction of the movement axis (200). Also, the key module (100) comprises a contact element (120) formed and arranged for establishing electric contact with the contact nose (140). Moreover, the key module (100) comprises the housing element (130, 110) for accommodating the contact element (120), the contactor unit (115) and the actuation element (105), wherein the actuation element (105) and/or the cam nose (135) comprises at least one constructive element (400) formed to deflect the contact nose (140) from a rest position adjacent to the contact element (120) in the direction along and/or transverse to the movement axis (200) upon a defined movement of the actuation element (105), then abruptly release it so that the movable contact nose (140) returns to the rest position and strikes the contact element (120) and/or the housing element (130, 110), wherein electric contact with the contact element (120) is established and acoustic noise is produced.

Electrical mechanism, which has an axial axis in which are arranged: a rocking lever configured to adopt a first position and a second position of electrical connection or disconnection; a striker configured to engage with the rocking lever in the first position and in the second position (P.sub.2); an actuating device configured to transmit an actuation force to the striker so that the striker engages with the rocking lever and changes the position thereof; and a spring configured to disengage the striker from the rocking lever once the actuation force is released. Two contact points for transmitting the actuation force are established between the striker and the actuating device of the electrical mechanism.

A battery distribution unit includes a housing having a bottom mounted to a battery case of a battery module and having a component cavity with a contactor therein. The contactor has fixed contacts having terminating ends extending from a bottom end of a contactor housing. The BDU includes terminals at the bottom end of the contactor coupled to the terminating ends and a heat exchanger cap at the bottom end of the contactor. The heat exchanger cap is provided in the component cavity in thermal communication with the fixed contacts and in thermal communication with the battery case of the battery module to dissipate heat from the fixed contacts into the battery case of the battery module.
