Video Transcript for Review of Bulldog Replacement Extend And Retract Switch For A-Frame Jack - BD500363

Hi, everybody. Andy here with And today, we're gonna take a quick look at this replacement Bulldog extend and retract switch. This is going to replace the extend and retract switch for your Bulldog powered A-frame jacks. Now, for your reference and on your screen, I am including the model numbers of the A-frame jacks that this switch fits. And just to go over some measurements that you might find helpful, I'm gonna be measuring the switch face.

So, looking at the height of that switch face, we are sitting right at, I'm gonna say right at an inch and 7/8 tall. And then looking at the width, we are sitting right at 15/16 of an inch wide. And then looking at the switch body itself, I'm just gonna look at the height here real quick. So, I'm gonna be measuring from the top and bottoms of these clips here. So, let me go ahead and line my ruler up.

It's probably gonna be easier if I do it this way. So, it looks like we're sitting pretty close to an inch and 5/8 tall. And then just measuring the width, looks like we are sitting right at pretty close to seven, looks like about 7/8 of an inch wide on that. Now, if there are some other measurements that you we're looking for that I did not cover with you today, take a look at this product page and we do have some additional measurements with diagrams that you can find, again, on our product page. And again, switch is gonna work very easily.

And since this is the replacement from Bulldog, you can have the confidence that this is gonna work with your Bulldog powered A-frame jacks. And instructions are included. Well, that's gonna conclude our quick look today. I do hope that it was helpful for you. Again, my name is Andy.

Thank you for joining me..

Replaces the extend and retract switch for your Bulldog powered-drive A-frame trailer jack (BD500185, BD500186, BD500187, BD500188, BD500199, or BD500200).


Order was shipped super fast!! The postal service had a slight delay but nothing to bad. Product arrived today and was just as described. Was able to get new switch installed in about 5 minutes and am back in service


Part came within a week. Easy install.

After a year, the cover bag dry rotted and fell apart. I ad to replace the foot of the jack for better stabilization. Then over time the aluminum pipe for the pin began to tear causing the pun to be lodged in the foot pole. The motor still ran great. I used this jack everyday for a food truck for the year, but in the end I had to replace it due to the foot pole getting bent. I would still recommend this product, just not for everyday use.

The switch I ordered was as expected; an exact replacement part. ETRAILER is one of few places I was even able to find the switch! I received a phone call from them to confirm that the shipping details were in order and the part was delivered complete with tracking information. They are my go-to company for all my RV needs. Great service!

Bob K - 06/24/2018


delivered on time with great instructions and installation was simple. Could not have been a better experience unless someone did the installation for me.

just fine - camping this week and used it often
jack n - 05/20/2019


Chrissy worked with me via emails & over the phone for at least a couple weeks (our schedules just didn’t work out at first), to get a simple power tongue jack switch ordered once she found the correct replacement that fit my needs.
I was a bit surprised upon receiving it because I only needed the switch “plate” that had fallen off without me noticing it after a camping trip. I received the entire “ switch” and researched my missing component further and found that it likely can’t be replaced in that manor.
I took a few minutes to take the switch housing off and made the required wire swapping, and it was done.
All worked as designed and it’s reafy for the next trip outdoors.

Thanks for your patience and knowledge getting me the part I needed Chrissy. Much appreciated.

Will be doing business again in the future if/when necessary.


Perfect fit and good price and shipping.


Product came in a timely manner. Haven't had a chance to install it. Manage to fix the old one and this will be a back up in case the old one falls apart. To darn old to be having to hand crank trailer legs down. Very impressed with what you have available in parts. Sure I will be ordering things from your company again.


Quick delivery time, came with instruction pages that I did not expect. Thanks etrailer.


I called because I wasn't sure what part I needed. Told them want was wrong and they directed me to this toggle switch. It was easy to install with instructions and came quickly. Works great a year later!


The part I ordered was received just a few days after I ordered it. I’ll order from this company again!




Product was identical to switch that was bad. We received the product in a timely matter. Would definitely buy again from E-trailer


Ordered my item received it very quickly.
Fixed my issue with my electric jack


Always purchase from e-trailer for parts. Generally they have whatever I need and prices are competitive.


perfect fit and function. I didn't have time to inspect the button for potential water entry points, as that's what killed the old one.


Received the switch in just two days. The instruction pamplet was the best I've experienced. Colored coded for easy installation.


Easy plug and play replacement.


This switch works fine, the motor turned out to be the issue.


The switch works Great. Instructions were very helpful...Thank You.


Great! No issue and exact replacement.


Product as described. Fast shipping and good communication.

Works as good as the day I installed it. Solid part!

  • Wiring Install Instructions for Bulldog A-Frame Jack Switch
    I attached a couple pictures that will walk you through how to install the Bulldog Jack Switch part # BD500363 that you are trying to install. You definitely have a short to ground on your current wiring setup and that is why the breaker is tripping like it is.

  • Troubleshooting Replacement Extend/Retract Switch for Bulldog Jacks # BD500363
    With the setup of the Replacement Extend and Retract Switch for Bulldog Jacks # BD500363, there is no fusible link, so that won't be an issue. There are a couple things to check to make sure the switch can function properly. First off, make sure that the wires are connected properly to the switch terminals. Also, it is important to make sure that the wires do not bind and are routed away from the jack screw. Lastly, I recommend making sure that the trailer battery ground cable is attached...

  • Bulldog BD500199 Jack Extends But Won't Always Retract
    According to Bulldog, what you are experiencing is most likely a ground issue, believe it or not. They suggest a couple of options to confirm this. 1) If power is getting to the jack, but it's not retracting, it's either a bad motor, a bad switch or a poor ground connection. The ground is the easiest to confirm, so start there. You can test this by turning on the lamp and extending/retracting the jack. If the lamp goes out while trying to operate the jack, it's a ground problem. Remove...

  • Troubleshooting Bulldog Powered A-Frame Jack that Stopped Working
    Either something happened to the wiring of the jack when it bottomed out or the switch went out on your # BD500199. The replacement switch is part # BD500363. If the light doesn't work either then I'd say it's wiring related and you'd need to go over it and check for anything obvious and fix. If the light does work and doesn't dim in any way when you hit the extend/retract switch then it would be the switch.

  • Troubleshooting The Bulldog Powered A-Frame Jack That Does Not Go Down
    The Bulldog Powered Drive Trailer Jack # BD500199 grounds through the mounting hardware. I would recommend running a jumper wire from the mounting flange of the jack to the ground wire on your trailer wiring to see if you can get it to work that way. The jack has an internal circuit breaker that automatically resets so the only other problem it could be is an internal problem. If that is the case you will have to purchase a new jack. If that doesn't work then the switch could be bad....

  • Replacement Switches for a Bulldog Electric A-Frame Trailer Jack
    It sounds like there may be a short in your Bulldog jack which could have been caused by excessive moisture from the rain. Also I recommend checking the wiring from the jack to the ground and power sources. The jack grounds through the mounting hardware so you may need to temporarily remove the jack (be sure to support the trailer another way) and sand away any corrosion. Also check for corrosion or damage to the power wire and where it connects to the battery. The light switch itself...
