Tutorial - Reed switch
Reed switch was invented in 1936 by Walter B. Ellwood in the Bell Telephone Labs. Reed Switch consists of a pair of ferromagnetic (something as easy to magnetize as iron) flexible metal contacts typically nickel-iron alloy (as they are easy to magnetize and doesn't stay magnetized for long) separated by only a few microns, coated with a hard-wearing metal such as Rhodium or Ruthenium(Rh, Ru, Ir, or W) (to give them a long life as they switch on and off) in a hermetically sealed (airtight) glass envelope (to keep them dust and dirt free). The glass tube contains an inert gas (An inert gas is a gas that does not undergo chemical reactions under a set of given conditions) typically Nitrogen or in the case of high voltage it is just a simple vacuum.

MIDI Solutions Relay
MIDI Solutions Relay Provides a contact closure which can be programmed to open or close in response to 4 separate types of MIDI events: Note, Control Change, Program Change, or a System Exclusive event such as MIDI Show Control or Machine Control. A fast reed relay is used for response time of less than 2ms. Relay contact is rated at 500 mA. Connects through 1/4" jack. Relay is programmed via the Processors Programming Tools software and retains settings even after power is removed. The MIDI Solutions relay unit is MIDI powered and includes an indicator LED. 4.3 oz. 4-1/2"W x 2-1/2" x 1-1/4"D.
