Connection Diagram

In this sample connection diagram it shows how LED can be controlled via relays, while this is a

bit of overkill for controlling LEDs its only meant to be an example. These relays can be used to

control lamps, or some other mid-voltage range appliances.

Plugging in an appliance

We will use "NO" for our example, using "NC" will simply reverse the logic, as explained

above.

We recommend using a swappable cable to do this with, as using a relay requires you to perform

some minor surgery on the appliance's cable. To plug in an appliance such as a lamp: Cut and

strip a portion of the positive wire so that you end up with two ends of the wire as shown in

Figure 2.
