if i did install rf receiver to light switch do i need to worry about the voltage coming through the wire ? currently my rf receiver turns on using 12v battery so if i connected that to the red wire of the light switch will it blow up ?

Yes! Red wire (120v AC) is much different that a 12V DC battery voltage.
