Any switcher with heavy enough contacts can be arranged to do the job, but Tim's answer is the simple one that works.
Relays with contacts that can carry the full battery load tend to be thirsty when operated, and will tend to negate any benefit. Switching to a smaller capacity reserve battery to get you back "might" be viable, but really it is simpler to notice that performance has drooped a bit and bring it in. Having a switchable reserve is probably a temptation too far.

HI the Action switch is designed for turning on ancillary items the relays are not highly rated for current draw. Simple solution install a larger battery or fit two.

Small relays can operate big relays, but its all extra weight and volume and complexity - extra battery or bigger battery is better. More run time plus less chance of it not working when needed.

thank you all for your replies to my question re. switch from one battery to another while boat is in the middle of the lake.it is obvious that the technology is not available at the moment, I will have to continue to connect two batteries in parallel, if you don’t ask you never know what is new and available.
once again thank you

We welcome well written contributions from Website members on almost any aspect of Model Boating with a particular emphasis on practical hints, tips, experience and builds.
In order to maintain a consistent standard and format, all suggestions should first be sent to me by Personal Message for approval in principle. Only a very limited amount of time is available for editing contributions into a suitable format for placing on the website so it is important that the material is well presented, lucid and free from obvious spelling errors. I think it goes without saying that contributions should be illustrated by appropriate photos. I shall be happy to give advice on this.
The Member Contribution area offers space for short informative mini articles which would not normally find a place in Model Boats magazine. It is an opportunity for Website Members to freely share their expertise and experience but I am afraid that virtue is its own reward as there is no budget to offer more material recompense!
I look forward to receiving your suggestions.
