Reed switch 1/2" 9,5x40mm NO with 1/2"-24UNS thread and 2,7m wires *new*

Reed switch is a most basic of magnetically operated switch. Bring a magnet close and the contacts inside close. Remove magnet and contact opens up. This can be used for picking up speed from spinning things or for handling positioning data.

Reed switch technical details:
