  • the cover element can be secured in the closed position by a locking mechanism. In the closed position, it is preferably held against the force of a tensioned opening mechanism, so that when the locking mechanism is unlocked, the cover element is automatically brought into the open position by the opening mechanism.
  • the printed circuit board can be at least partially encapsulated with the housing with the aid of a foam plastic in order to increase the mechanical shock resistance. It is also advantageous if the circuit board is screwed to the housing.
  • the cover element does not necessarily have to be extendable. It can also be movable back and forth between two positions without increasing the length of the device.
