When used with one of our in-line dimmer modules, a short press will turn the light on and off. A press and hold will dim and brighten the light.
Both versions must be used with one in-line dimmer module per circuit.
Intermediate switches need to be used when three or more switches are required to control the same light. Two-way switches are used at the start and end of the circuit, and one or more intermediate
switches are added to the middle of the circuit. Our intermediate switches can be found here.
Multiple two-way dimmer modules can't be used to control the same light. A two-way dimmer can be combined with two-way or intermediate switches to control the light from multiple locations.
Retractive and centre retractive toggles/rockers can be used for a multiple point dimming circuit when used with an in-line dimmer module (one per circuit).
All our dimmers have been engineered with anti-flicker technology. If flickering is something you're experiencing, please follow our mode setting instructions here.
