The Fibaro Dimmer module can be used with a variety of switch types.
This application note explains how the Fibaro Dimmer can be used with momentary, toggle and 3-position switches.
Note: The Fibaro dimmers cannot be used with existing dimmer switches or other 'electronic switches' - see the Switch types that cannot be used with Fibaro Dimmers section.
Toggle (Bi-Stable) switches latch in position. For instance when you press the switch to On, the switch physically stays in the On position. These are the standard light switches you’ll find already fitted in your home.
You can use these in two ways with the Fibaro dimmer, depending if you would just like On/Off control of the light or you would also like to control the light’s brightness from the switch
Using a toggle switch in this configuration will enable you to manually control the light On and Off, just the same as a normal On/Off switch.
As strange is it sounds, a toggle switch can also be used with the Fibaro dimmer to control the lights brightness. Although this may at first appear a little unconventional.
Momentary switches, also known as Retractive, Mono-Stable or Bell-Push, only remain in the On state while you press them, they return to the Off state when the button is released. This doesn't mean that you have to keep holding the button to keep the light on. The Fibaro's internal controls automatically keep the light on when the button is released.
A 3-position momentary switch has 3 positions and is also known as an ON/OFF/ON switch. It normally stays in the central (Off) position, you can then press the top or bottom parts of the switch to move it into the On positions. As this is a momentary (retractive) switch, it only remains in the On state while you press it, it returns to the central Off state when the button is released.
More information on the Momentary Switches we use and where you can get is available in application note APNT-25: Momentary Switches.
You should only use the switch types shown above with Fibaro dimmers.
Other switches such as conventional dimmer switches and 'electronic' switches should not be used.
Conventional dimmer switches cannot be used as they will conflict with the dimming action of the Fibaro dimmer.
These are switches such as touch sensitive switches or switches with LEDs.
They cannot be used with the Fibaro dimmer as the Fibaro dimmer switch connections (S1, S2 & Sx) cannot provide power to the electronic switch.
