Listed here is a good used Volvo S60 / V70 XC70 S80 Headlight switch.  All tabs in-tact.  This unit functions properly.   Please see picture - and compare your original part number, as there are several different variants of this switch.  

This unit was checked for normal function, it works great!

 List price at Volvo USA was previously nearly $280! get this one for less than you would pay in tax at the dealer! I only sell the OEM units, never aftermarket so they are the same quality as your original. 

I will offer a 30 day functionality guarantee ,Thanks for looking and good luck!
