Introduction: Fischertechnik 3 Way Switch
How to create a fischertechnik 3 Way Switch!
I play with different educational manipulatives for a living. (Visit www.weirdrichard.com). Over the years I have built different themed models using all sorts of toys. This instructable will describe how to create a fischertechnik 3 Way Switch.
This is a cool assembly. Pushing down on the large pulley will engage a touch sensor. Turning the pulley in either direction will engage separate touch sensors. This assembly has some nice control applications.
Disclosure: When I attended the ft fan Convention in Moershausen (Sept 2008) I ran into a fellow who had this assembly as part of his model. This is a slightly different version of it, but I want to credit Kehrblech for the model. (You can see his model here: http://www.ftcommunity.de/details.php?image_id=15397 ).

Step 1: Gather Elements:
You will need to gather your elements. The fischertechnik elements are available
from a range of kits available from ebay, Craig's List, or fischertechnik retailers. Elements can be purchased individually from www.fischertechnik.com.
1 Large Pulley 60
1 Hub Nut
1 Link 15
1 Spring Cam
1 Building Block 15 with Bore
1 Bottom Plate 30x90
1 Building Block 30
1 Building Block 15
1 Flat Hub Collet
1 Clip Axle 45
1 Crank Shaft
1 Building Block 5 with two Pins

Step 2: Construct Switch
The following steps demonstrate how to create the assembly.
This assembly can be integrated into a wide range of robotic devices!
