These switches are for guitars with thin bodies, such as SGs and Jazzmasters. These function exactly the same way as straight toggle switches, but with the lugs coming out of the switch at an angle so that the switch length does not exceed the depth of the body cavities of the guitar.
These switches come with two output lugs to run to the jack, a ground lug, and two input lugs for the pickup inputs (via the volume pots, usually).
