Newbie asks advice how to turn on/off Sub

[Wax Savage]

Here’s the issue, there’s not enough room to install a Universal Remote Control on/off Kit in my new 2.75” dia. WTC.

I planned on using the SPST switch on/off supplied by R&R in my new WTC but, it is only rated for 3 amps at 12v DC. Any switch will need enough Giddy-up to power two brushless motors each with an esc, a brushed ballast tank water pump with a (brush) esc, four mini-servos and whatever current is consumed by the radio receiver. How many amp SPST would you think is appropriate?

Center your transmitter sticks and pots before powering up, and you'll be fine.

This.

The switch can "carry" more current than it can "switch". With all controls at their idle point, i.e., control surfaces centered, pumps and drive motors off, the only current flowing when you power up the cylinder will be idle current for the receiver and servos. Make sure to turn the transmitter on first and turn it off last.

Thanks for the response. You satisfied my concern about any electrical overheating or failing.

Merry Christmas to all
