SAFTZ Home or Business and Prevent Accidental Switching

Picture of SAFTZ Home or Business and Prevent Accidental Switching
Fail-Safe systems technology has long been the domain of corporate, military and governmental organization that demand that highly sensitive, complex, and/or dangerous operations be qualified and confirmed. The danger of triggering these processes accidentally cannot be underestimated.

The R&D team of SAFTZ has made these type of processes available to the general public.

In this effort, SAFTZ has designed several key products. We believe that switches should never be accidentally thrown.

In this walk through, you will see the process and fabrication techniques used by our team to create a working prototype of our commercial product.

Step 1: Collecting Materials and Tools

For this project we used the following tools:

Screwdrivers (Phillips and Standard)
Wire Cutters
X-acto Knife


1"x1" wood for creating border for key switch
Small piece of Plexiglas
light switch with metal shroud
PVC Pipe
Thin Metal Pipe (for using the switch)
2x Lamps
Assorted Wires and Wire Nuts
Various Screws

Step 2: Standard Switch, Drill Holes

We are going to start with our standard switch first.

The first thing you want to do is to drill a hole in the board, so that you can feed wires through to the switch. You might find it useful to place the shroud on the board first, and to use a pencil to mark where you want to drill.

The hole doesn't have to be very large, just big enough the feed the wires from the lamp through for the switch.

Step 3: Wire the Switch

the first thing you will want to do, if you lamp has a standard plug, is to cut it off. You then will strip both wires at the end, so that they can be fed into the switch. The contacts are spread out, so you might find it useful to split the wires down the middle as well.

Feed the wires through the rear of the board and use a Phillips screwdriver to mount the wires to the contacts.

Step 4: Mount the Switch

Now, you can mount the switch to the shroud. This also might be a good time to plug in the lamp, and make sure the switch is working properly.

Very odd.

Er... safer?

Making it easier to throw the switches makes them safer - you don't have to grope in the dark to find the key, you don't run the risk of walking into a dirty great pipe.

Key-secure switches already exist anyway - they use a slim T-shaped key that costs pennies to produce, rather than an expensive car-key.
