I am changing light switch from dimmer to ordinary switch (off/on) but wires also have 'yellow' one. There are 2 switches for this one light in the room and am supposing that this is additional wiring for this.
In the switch I have red and brown from ceiling and red, blue and yellow from floor.
Do i need switch with three 'holes' or the standard, one for red and one for brown/blue?
