Thanks for the post,

It's tough to say if a replacement switch is available and will work, without seeing the switch itself.

First, try contacting Search directly at 1-800-755-5043 to see if they can recommend you anything at all, or perhaps give you a referral of another source that may have it.

Next, I'd try another vendor like Eurton Electric, you can visit their website by clicking the below link:
