Basic Switch

Building a Basic Switch

The Basic Switch provides 4 lights (LEDs) which will show the "high" or "low" voltages on the output lines of the CBL, CBL2 or LabPro. One of those lines is also connected to a relay, which can act as an on-off switch for low-voltage, low current circuits.

The circuit should only be used to control low-current, DC circuits. It should never be used with AC or other potentially high-energy sources
