DIY Soda Can Organizer/ Dispenser

To save space in our tiny refrigerator, I made an acrylic soda can organizer/ dispenser. It holds 7 soda cans and is gravity feed. The dispenser base has a small channel that securely rest on the fridge divider railing to prevent it from sliding out during travel. Here's how it looks like.

Adding a Wireless Remote Control to the Macerator

Dumping the holding tanks with Roadtrek macerator system is pretty easy and quick, although the switch location which activates the macerator pump is not very ideal. The switch is located on the frame of the driver seat facing the driver side door. To operate the macerator you have to open the driver side door and reach for the red switch, and since it is momentary switch you have to hold the switch the entire dumping process. It is a minor inconvenience, but leaving the driver side door open while dumping the holding tanks is an open invitation for flies/ bugs to get in the RV not to mention when it is raining...I thought, there could be a better solution.

At first I thought of replacing the momentary switch with an on/off rocker switch, but someone could accidentally flip the switch on and run the macerator dry causing early macerator failure. RT used a momentary switch there for a reason.

My solution is a wireless on/off momentary switch. Again I decided to go with a momentary switch on the wireless controller as for the above reason.  The wireless controller and remote transmit/receives analog signals which is prone to radio wave interferences that could inadvertently activate the controller. Although I am using a separate switch to power the wireless controller, there is always a chance of forgetting to turn it off.

I got the wireless remote switch from EBay. I've seen Amazon carries them but it is a different brand. Wireless momentary switches. I bought the less expensive controller with a lower load rating internal relay and used an external heavy duty automotive relay instead as pictured below. It would be easier and cheaper to replace the external relay if it fails. An inline fuse is needed for safety as you are tapping power from the 25-amp fused line.
