Electricity Merit Badge Kit

This kit provides you with all the parts needed to build the switch in Simple DC Circuit and an electromagnet, and the parts to show that the switch and electromagnet works (two lights of any odd color, 4 AA batteries, and a 4 AA battery holder-- which supplies the perfect voltage for working with IC chips in the future). You will need a flat head or Phillips screwdriver to assemble the switch. Wire cutters may be needed when building the electromagnet, or if not all of the 15 ft of magnetic wire is used (old metal scissors may work)-- in fact 7ft is all that you really need.

Please review the notes below to keep the lawyers happy. By purchasing, you acknowledge that you read the warnings below.

Notes: The switch is mostly the same as shown on the website (which was the prototype). The only difference is in the washers used for the switch operating arm. Instructions are provided for building the switch. Instructions for building the electromagnet are provided here.

There is a risk of splinters and the edges of the metal strip can be sharp (even after griding/filing), so handle with care. Children under ten (or those who don't read instructions) should be supervised when building this kit. Due to choking hazards, children under 5 should not be in the same room as where the kit is being assembled.

The switch is only intended for switching DC current from a battery or isolated/ungrounded DC power supply under 12 volts. Do not operate switch with AC current. USE ONLY WITH PROVIDED BATTERY PACK AND 1.5 VOLT ZINC-OXIDE, ALKALINE, OR NICKLE-METAL HYDRIDE (NiMH) BATTERIES! Disconnect circuit immediately if batteries (or any other part of your circuit) becomes warm to the touch.

Never hold the positive and negative leads of a battery (or other power source) in opposite hands (or other parts that cross the heart) while hands (or other body parts) in contact with leads are wet or cut (as in cut and bleeding). Never attempt to puncture the body with the battery leads. Doing these is about as brilliant as playing chicken with an oncoming train while riding a bicycle.
