Combination button 3Plus in analogue button design for rear installation in Comelit audio and audio-video door stations, mailbox systems and door stations from third-party manufacturers up to a maximum material thickness of 2.5mm. The button can be used in SB, SB2 and VIP systems. It consists of a nameplate (which can be changed on the front) and a call button made of stainless steel, whereby the material and colour are interchangeable (Art. 3060A in aluminium, Art. 3060B in brass). If the installation takes place behind a metal plate smaller than 2.5mm, an appropriate adapter must be used to compensate (not included in delivery). The maximum current at the contact is 2.5A and the maximum voltage at the contact is 24V DC. The button is delivered without nameplate lighting.
