SWITCH BLOCK OVERVIEW

The Switch Block can switch up to four devices that consume substantial currents - up to 10 Amps with no cooling.

How Do I Use This?
The Switch Block provides the same functionality as the switches on some of the other Blocks (Poly Block, Stepper Block, etc.) but can accomodate much larger currents. Signals to the inputs should be digital values - 0V or 5V. The outputs are switches to 0V. This means that a device you want to control must be connected to power (+V or 5V from the Switch Block, or from an external power supply) and the Switch Block output on the ground/negative side. When an input receives 5V, the corresponding switch is closed, connecting the corresponding output to 0V and turning on the device.

Applications
- Power Heavier Duty Devices. If the large lamp, valve, motor, fan, etc. you want to control draws more than the 2 Amps that the normal Block output switches are capable of, you'll need to use the Switch Block to avoid damaging the microcontroller.
