This simple on-off switch is rated for 20A at 12V (with cover) or 10A (without cover). These toggle switches come with those missile switch covers that make your project look like something out of a spy movie. They're also a great safety feature to ensure that you don't accidentally fire the missiles (or whatever it is your switch does). As if you needed any more convincing, they're also illuminated with a small LED at the end of the switch.
Please note. The version without a cover does not have a negative terminal built in. See the attached images
