Buttons & Switches
The Buttons & Switches library contains two-state controls that change their
state when you click on them. The block output is
0 when the block’s state is
“off” and
-1 when the state is “on.” The blocks in this library differ in cosmetic
ways, such as the image(s) shown on the block and the changes in the block’s
appearance after you click on it. The next sections describe how to customize
buttons and switches, and how to change the output values from buttons and
switches.

Switches library, using its
