Breadboard-friendly SPDT Slide Switch : ID 805 : $0.95 : Adafruit Industries, Unique & fun DIY electronics and kits
These nice switches are perfect for use with breadboard and perfboard projects. They have 0.1 spacing and snap in nicely into a solderless breadboard. They're easy to switch no matter what size fingers you have, but not so easy that they'll get flipped by accident. Work great as on/off switches or selector switches, the middle pin is connected to either the left or right pin depending on which way the slider is pushed.
