Greetings. I'm a beginner and I'm trying to build a very simple arduino-controlled switched 110v outlet. I thought I could use the JZC-11F relay (https://www.sparkfun.com/products/100) that comes with the SparkFun kit, but I now realize that it is a SPDT relay. I only want the outlet to turn on and off.
I understand that this relay has a COM (common), normally-closed (NC) pin and a normally-open (NO) pin. My intention was to wire up the line (black wire) in an old extension cord to the COM and NO pins. When I apply voltage to the relay it closes and the outlet (female) end of the extension cord turns on. Its about as simple a project as you could imagine, but it does involve 110v.
Since I am not connecting the NC pin, is it safe to just put electrical tape around it? Or can I just snip the pin off with wire cutters? Or is there another option? Or is none of this safe, and should I go out and buy a SPST relay?
I'm using the following two articles as reference:

Any advice would be appreciated.
