1977 240D Hazard Flasher Switch
 

hello, i have a 1977 240D, and the Hazard Flasher Switch has gone out. I have been looking for a replacement and the only switches i find have a different pin configuration ( 1 extra pin ) and a copper piece in the center that is not on my switch.

my question is will these switches work, and if not, what can i do?

thanks

this is the switch i am finding

the side with 5 pins, mine does not have the middle pin of the 3 pin group. Also, the copper piece i am assuming is just holding in the small bulb inside the switch. my switch just has a black plastic piece that slides in/out.
