This single-pole, double-throw (SPDT) momentary switch can be used as a general-purpose micro switch, but the 2"-long lever arm makes it especially useful as a simple tactile obstacle-detector for your robot. The switch body dimension is 20.0 x 6.4 x 10.2 mm (0.79" x 0.25" x 0.40"), and the lever arm is 50 mm (2") long. This three-pin switch can also be used as a two-pin single-pole, single-throw (SPST) switch that is open or closed by default, depending on which two pins are used.

Dimensions (in mm) of snap-action switch with 50mm lever: 3-pin, SPDT, 5A.

For a more sophisticated tactile sensor, see Pololu's force-sensing resistors.
