Video Transcript for Review of etrailer Camper Jack Parts - Replacement Rocker Switch - EJ-3520-PSW

Ellen: Hi, everyone. I'm Ellen here at Today we're taking a look at the replacement power switch for Ram electric trailer jack. Now, this is just going to let you operate that jack by running it up or down with this rocker style switch, so it's going to be a direct replacement for your electric jack, part number EJ-3520-BBX.As far as the measurements for this and the overall size, the outermost edge here is going to be about one and a quarter inches by about an inch. The cutout, this will actually fit into, you can see on the on either side there're those little spring clips to hold it in place, so when you push those down they provide that tension to keep it there. But as far as the rough size that this will fit into, it's going to be about an inch and an eighth to maybe an inch and three-sixteenths by about an inch and seven-eighths.

The overall depth for this total is going to be about one and one- to three-eights inches. The actual mounted depth or what will actually be in our jack to be about an inch and a sixteenth.This is rated at 16 amps for 2,250 volts AC, and then 16 amps at 120 volts AC as well. You can kind of see it stamped on the side there, so should get you back out and rolling with your trailer jack. That's going to do it for our look at the replacement power switch for the Ram electric trailer jack.

Replaces the power switch on your electric A-frame jack with footplate (EJ-3520-BBX).


Bought to replace a broken switch on a RAM EJ3520 electric trailer jack. Simply popped out the old switch with a screwdriver and moved the wires from the old switch to the same positions on this one. Works & fits perfectly.

1 year later, still working.

We use these on the back platform of our travel trailer to hold our two e bikes ( which are heavy) and they perform well.


exact replacement for 2017 ram jack.


Not a direct replacement for broken switch. Ordered knowing this. I had to jumper pins to make it work with my jack. Little extra work but got the job done.


This is not the switch I ordered
I ordered
a 6 terminal switch you sent me a 5 terminal switch
I waited since may and get the wrong part , not impressed
I would like my money back

It is frustrating to receive an order an it is the wrong part. We can take care of this for your and I will have our customer service team reach out to you.

Bought this to replace a faulty switch in the trailer jack for a 2017 Forest River SM19 travel trailer. Haven't installed it yet. Shipping did take awhile. Ordered 10/6, received 10/19.

It has been a year, still works great!!!

It took months to get this switch. I don't blame etrailer, but I actually sold my trailer since I ordered it. That's how long it took. Oh well.


Excellent replacement for the original power switch.


Also work is perfect fit and good time Delivery

Excellent service.


Don't know yet if it's the correct one. But it looks the same.


The switch works great and fit great was a direct replacement for the switch in my Ram tongue jack and give it 5 stars
My only reason for not ordering from etrailer more often is shipping besides having to pay for shipping they use USPS and it takes a week to get the part


Excellent perfect fit and function


Great service. Part was exactly as described and arrived without hassle. 1/2 the price of my local dealer. Replaced my broken switch with ease.


Let me start off by saying I have not had the time to install this switch yet. I'm glad
I was able to get it in the 1st place. Before I ordered it from etrailer I tried to order from my RV dealer. That didn't work out. Then I tried the manufacturer of the electric
jack. Still can't get their phone number. The customer service person from etrailer was great in regards to helping by insuring I ordered the right part. I also got instructions on their web site on how to install. The prices were fair including shipping. Two items were bought. GREAT !!!


It was great shopping and finding what I needed


5 stars


Switch was exact fit, still works great and gets a great deal of usage.


Couldn't appreciate the switch much since it still didn't work. The old switch face was cracked around the edges and was loose feeling. l don't have an ohm/volt meter to further research. l'm debating a manual one or a new power jack. That Bull Dog one you sell, may be my next order.

Thank you for your review. This switch is a specific replacement part for the RAM electric trailer jack part # EJ-3520-BBX. The EJ-3520-BBX model offers 25 1/8 of lift and handles 3.5k weight. The closest bulldog jack we offer to your current jack, is part # BD500199
Bulldog Powered Drive Trailer Jack - Drop Leg - A-Frame - 22" Lift - 4,000 lbs - Black
. This bulldog jack offers a 22 lift and can handle up to 4,000 lbs. I have attached a link for it below.

Worked Fine
Steve B - 07/23/2021


My electric Jack would go down but would not go up. Ordered this switch and replaced the old one, the Jack works perfectly now. Fit and finish is exactly like the factory switch. It took all of about 5 minutes to replace the switch. "I love my electric Jack".
