Abstract
A key arrangement includes an activation element, a switch, a mechanical counterforce generating device, and a permanent magnet arrangement. The switch has at least a first state and a second state. The activation element has a basic state and an activation state and is configured to, in case of activation by a user, permit a movement from the basic state into the activation state, and in case of the movement into the activation state to permit a change in the state of the switch. The mechanical counterforce generating device is configured to generate, in case of an activation of the activation element, a first counterforce at least in certain areas. The permanent magnet arrangement is configured to generate, in case of activation of the activation element, a second counterforce at least in certain areas.
