FEATURES
The reed switch is an electrical switch operated by an applied magnetic field. It was invented at Bell Telephone Laboratories in 1936 by W. B. Ellwood. It consists of a pair of contacts on ferrous metal reeds in a hermetically sealed glass envelope. The contacts may be normally open, closing when a magnetic field is present, or normally closed and opening when a magnetic field is applied. The switch may be actuated by a coil, making a reed relay,[1] or by bringing a magnet near to the switch. Once the magnet is pulled away from the switch, the reed switch will go back to its original position.
The reed switch included in the Electronics Component Kit is normally open, closing when a magnetic field is present.
An example of a reed switch’s application is to detect the opening of a door, when used as a proximity switch for a burglar alarm.
It can be combined with the included round magnet to create open/close switches, revolution counters in bicycle wheels and more.

We will be publishing more information about each component and example projects.
Modern microcontroller projects require the use of multiple voltages to combine different parts. It is very common to prototype circuits that require both 5V and 3.3V (i.e. Arduino projects that use sensors or micro controller boards like chipKIT that interface with 5V devices, etc).
We created a breadboard power supply stick that provides both 5V and 3.3V. The voltage selection is user selectable, so you can power both power buses on a breadboard with same 5V, same 3.3V or mix 5V and 3.3V on the different buses.
The product comes fully assembled, except for the male headers that are provided unsoldered. Breadboards are slightly different in size, so doing the final soldering we can assure you have the best fitting product to your specific breadboard. Differences are tiny, but you can find the best fit doing the final soldering.
First, unpack the kit
Start by breaking the male header
Insert 2 2-pin male headers on one of the power bus, then insert 2 other 2-pin male headers on the other power bus.
Insert the power supply stick matching the 8 pins to the 8 power holes and solder
Solder the 2 3-pin voltage selection headers, then place the jumpers based on your voltage needs. Plug a 7 to 12V DC supply to the 2.1mm barrel jack and you will have a working breadboard power supply stick.
