Up for sale is a used MTH 031 LH remote switch in very good physical condition, but not working for me. I sold a couple like this before that the buyer got working right away, so clearly I'm missing something simple here. 

Please see pics and judge condition for yourself. Check my feedback and buy with confidence. I pack everything I sell carefully so it arrives in the same condition it left in.

I will happily combine shipping for multiple purchases made at the same time.

Thanks for looking!
