This listing is for a brand new telegraph key switch. This simple switch acts just like a telegraph, closing an electric circuit whenever the key is pressed. Works and looks great for science projects to show how a simple circuit works. Also good for anywhere you need a basic momentary switch. Instructions on how to wire a simple circuit available upon request. Larger quantities available upon request. Be sure to view my other items at the ScienceSupplies store.
