Most likely it will work but the writeup will need to be updated for Hammer. I am happy to do that if someone provides pictures and needed details.

The main difference is that the switches in your machine receive line AC voltage. The current version of the receiver I used, only states output relay capability as 10A @ 14VDC. I know most of these relays can handle AC and DC voltages, as shown in pic below.

There are many available on Amazon but I prefer to buy from an established business. I have a message out to them to confirm relay capability. I will keep all posted.
