    Dual Optical Switch, Low Profile (2 pack)

Dual optical interrupter switch (has two channels--very unusual and hard to find!), with low profile. Great for use with small mouse encoder discs. With some careful alignment of the disk in the slot, you can build yourself a very inexpensive quadrature encoder that will be the envy of friends and family.

Sold in packs of two.

Comes with basic datasheet info so you know what lead goes where. Add an inexpensive optical odometer encoder to your robot.
