About product


This wall-mounted printed circuit board connects a single or double bus push button to a flush-mounting box. It is also suitable for use on uneven walls. Would you like to be able to re-use existing flush-mounting boxes? Then you can click together several wall-mounted printed circuit boards with bridges. It is easy to combine with other Niko flush-mounting devices. The connector has 4 poles. The bus push button is mounted with the click mechanism. The single, wall-mounted printed circuit board is attached to the wall with screws or claws.

The Nikobus reference codes no longer feature in the Niko catalogue. We are no longer actively promoting the Nikobus products. We do, however, still make them in order to source spare parts or to complete an existing installation. For new projects, we recommend choosing Niko Home Control.


Simple wall-mounted printed circuit board with base for Nikobus push button. A wall-mounted printed circuit board includes all the electrical and mechanical components required to connect one or several push buttons to the Nikobus installation. Niko offers horizontal, vertical, single or multiple printed circuit boards. Choose the type of printed circuit board depending on the number of action buttons required and on a horizontal or vertical assembly. The printed circuit board can be easily replaced by a larger one at a later stage if the need arises to expand the installation. The 4-pole plug-in connector has two connections for Nikobus and two for LED or infra-red push button bus power supplies. 1 mm A 4-fold plug-in connector When mounting in a flush-mounting box with grip surfaces, use claws that can be rotated open using screws with a slotted screwhead (slot 0.8 x 5 mm). The claws, which have a depth of engagement of 31 mm, turn back completely when loosened.
