Gira series dimmer

The Gira series dimmer is a touch dimmer that allows the user to control two lights or light groups independently of each other. When normally two individual dimmers are required each in their own flush-mounted device box, the Gira series dimmer offers the dual function from one flush-mounted device box.

Ideal for retrofitting: an existing series switch can simply be replaced with the Gira series dimmer. The Gira series dimmer is available for all Gira design lines.

Special features, details

Two universal dimming channels are provided for switching and dimming various light sources such as light bulbs, HV halogen, LV halogen with Gira Tronic transformers or LV halogen with conventional transformers. Both channels control different load types entirely independently of each other. Each channel can separately store a memory value as an individual activation value.


The Gira series dimmer is operated by gently pressing the corners of the button. Channel 1 is controlled on the left, channel 2 on the right. The top is for switching on and dimming up, while the bottom is for switching off and dimming down.

By pressing and holding (approx. 4 seconds) the button half way up, the currently set brightness is saved as a memory value, either on the left half for channel 1 or on the right half for channel 2.

Both dimming circuits can be synchronously dimmed up or down by pressing the central axis marked with a line, depending upon whether the upper or lower area is pressed. When the entire surface of the button is pressed and held (approx. 4 seconds), the memory value for both channels is saved.

Both outputs are always synchronously operated and both memory values stored via a connected auxiliary unit.
