Remote water pump switch - latching relay?

Intellitec water pump controller- single wire to switch (which just grounds). Why reinvent the wheel.

Thanks for the suggestion. To avoid reinventing is why I asked. That claims "Negligible standby current", which means it's not what I'm looking for. There's no reason to have any standby current.

Also, the DEI 611T Relay Timer is an option, but again, it's solid state, and I'd rather just have the mechanical ratchet type. The solid state devices are more sensitive to spikes and other misc. issues found on an RV 12V electrical system.

Get real!
The Intellitec Monoplex Controller has less than 2 milliamps standby current. Your batteries loose more charge, just sitting totally disconnected, than that. I doubt very seriously that the average RVer caries a meter that will detect, much less measure, a current that small.
