Switches
In principle, the type of switch can be selected freely. However, the Smart Building Automation system uses pushbuttons for control. Pushbuttons with at least 2 to 4 pushbutton functions per unit (corresponding to one flush-mounted box) are recommended.
Since only 24 V signals are switched via the pushbuttons and sensors, there are no special requirements regarding their current-carrying capacity.
Example:
The following pushbuttons are planned for the bedroom:
- 1x 2-way pushbutton at the entrance for the ceiling light. A double-click switches off the dimmable reading lights and the ceiling light.
- 1x 4-way pushbutton and 1x 2-way pushbutton next to the balcony door. Two pushbuttons are used for UP/DOWN control of each of the two shading elements, one for the outdoor light, and one for the ceiling light.
- 2x 2-way pushbuttons, one on each side of the bed. One pushbutton is used for the dimmable reading light and one for the ceiling light.
- 1x 2-way pushbutton behind the bed for special functions. These functions could normally also be implemented using a double-click or long press. In this example, the additional pushbutton is included to demonstrate the use of the Schrack Smart Building Automation Digital Module "D1180".
