The PBP-05 bistable relay is used to control lighting or any other device by means of monostable buttons connected in parallel. The device has two independent channels with a load capacity of 5A. The relay allows control by supplying the L phase potential or neutral N potential to one of two inputs. The trigger input design enables operation with backlit buttons (also with LED backlight). Output relays are adapted to work with loads in the form of modern LED sources. The device is adapted for mounting in an installation box fi 60 (preferably deepened or pocket).
