Electrical Wiring in the Home/combo switch


QUESTION: I have a box with 2 switches in it. One controls a fan the other a light.
I'd like to change the light switch to a combo.

The wiring now shows 2 reds and 1 black coming into the box.
One red ,one black to the dryer switch. Then the black from the dryer switch over to the light switch. The other red coming in directly to the light switch.
There does not appear to have any neutral wires

QUESTION: a combination light switch and a plug all in one receptacle. similar to what's in the photo.
Ut as I mentioned I only have the 3 wires coming into the box

Since you have 2 reds and a black in the box, are both NATURAL red conductors?
If so my guess is that your switch is wired with individual conductors pulled through conduit/pipe, rather than a multiconductor cable.
You will have to drop/open/remove the light and pull an extra white conductor from the light to the switch.
Otherwise you will have to run an additional cable from somewhere.
Isnt there a laundry receptacle?
A receptacle in the laundry should really be on a 20-amp circuit.
