For security reasons key switches are combined with a lock for access control. The switching process can therefore only be carried out by a group of authorised persons with the aid of the appropriate key. The JUNG key switch is available in the versions of a blind switch (for example, for roller doors) and a 2-way switch, in each case with protection against dismounting.
It is available in the design of the A, CD and LS series and in the WG 600 and WG 800 splash-proof surface-mounting ranges. In all the series there is also a version with a flat cover without rosette.
