New safety timers for softlab hot tools

I have installed two simple safety timers for flat iron and clothes crease at softlab, so when they are used properly they will cut power after at most 1 hour from those hot tools. Please do keep those dongles attached to cords at all times, so pull them out with cord when you are finished, thank you.

Basic usage instructions:

1. Plug cord with safety switch attached to it to power outlet
2. Press the one button on safety switch for adding 15 minutes of power, maximum 1 hour possible at any given time
3. Unplug safety switch with cord attached to it from power outlet when finished.

Safety switch has four light segments indicating approximate time left, one quarter is fifteen minutes.
