Hi there,

When you order 3SU1050-5PF01-0AA0 you will get a key-operated switch with lock type BKS, S1. The key of this switch also fits to all other key-operated switches with lock type BKS, S1.

If you purchase for example 5pcs 3SU1050-5PF01-0AA0 you can operate all of these switches with the same key.

Further for BKS, CES and IKON key systems it is possible to realise master and master-pass key systems. For details see catalog IC10 2017 page 13/81 (chapter 13).

thank you all for your help.

one last question:

can we modify the following switch to have the Key Removal in both positions (on and off) ?
