So you want it on constantly then? Does this camera have a parking mode feature?

actually i want both ,

When i need parking mode

with a ON off ON switch i send constant 12v voltage into the camera.

I think the single pole double throw switch you pictured should work fine for your application. You could accomplish the same by using just a single throw (on/off) switch, you would just have to turn it on and off every time. Lless wiring to mess with.

A single pole switch isn't a good idea. With the cam on the output of an ACC circuit, feeding power into the cam from another source with the car swirched off would also back-feed that circuit. With a DPST switch, when you power from the full-time source, the ACC circuit which normally feeds the cam is isolated. Switching theopposite way isolates the full-time source and connects the ACC circuit. Done forget to fuse both sources ;)

Either approach would work. With the diodes on the regular on off switch you should get any back feed issues. Less wiring, easier install. You even have the anode/cathode the correct direction.

I had mine set up this way for a while.

I used a SPDT switch. That type of switch has a center lead and 2 positions. In one position the center is connected to the left lead, and in the other position it's connected to the right lead. You just have to put your ACC power into left, and BATT power into right, and you can choose which source gets sent to the camera. There's no center position, so the switchover is fast enough that the camera keeps working as long as the 5V converter or camera can handle the very short power dip

Don't use a switch type that will connect both ACC and BATT at once, because you'd be effectively combining 2 circuits and who knows what bad things could happen

Just to be clear, on the picture below it's 1-Battery 2-output to camera 3-ACC
Then the - line from the camera goes to ground
