Reed Switches

Sports, Recreation, Hobbies and Toys

The sports and fitness industry has seen a lot of changes lately by their move from using analog instruments and gauges to intelligent electronic controllers which give the user a lot more information on calories burnt, distance run etc. Reed Sensors are used in a variety of sports equipments for passing on signals to the controller which in turn do the processing and give the user intelligent outputs.

With the advent of intelligent toys and engineering kits, reed switches are also used by hobbyists. Reed Switches can be used to make LEGO-Mindstorms sensors to sense rotation, position and temperature. Commercial grade reed switches can be used in dolls and toys for position sensing. The most well known reed switch and reed sensors are listed below. We have also suggested few of our products for use in each application, but this does not mean that the other products in the same product category will be unsuitable.
