Reed switches work on a basic principle whereby the reed switch is a hermetically sealed glass tube containing two ferromagnetic reeds that will actuate when in the presence of a magnetic field. The magnetic field may be generated from a ferrous metal such as iron, a permanent magnet such as rare earth types and/or an electromagnetic coil as used in a reed relay.
Reed switches have various electrical properties such as their sensitivity range which is generally specified in ampere turns (AT). The AT or sensitivity of the reed switch refers to the open and close points of the switch.
When a reed switch is used in conjunction with a permanent magnet, it referred to as a reed sensor. Typically the reed switch is mounted to a fixed object and the magnet to the moving object. The strength of the magnetic field as well as the position and movement of the magnet relative to the switch will determine how many open and closure points will take place.
Example: Parallel movement of the magnet to the switch can produce either one or three switch closures depending on its distance from the switch.
Dimmer switches go bad, more often than regular switches.
What are Air Force types of ied switches
I have trouble understanding your question. But I think you are saying that you have two switches that control one light and want to know why it is not working. More than likely is that you have two way switches instead of 3 way switches installed. 3 three switches cost a little more and are a little more difficult to install but if you recently replaced these switches you may have replaced them with the wrong type.
All the switches to be tried first. 2 out of 3 must be switches of the ground floor room. So which ever doesn't work for the ground floor electronics must be first floor bulb switch J
Light switches can be purchased from SparkyDirect, they have a huge range of light switches other websites offering light switches are HomeBase, argos and ebay.
Reed switches were used in early keyboards, the two reeds sat apart until a magnet placed over them then they touch, circuit complete.
LAN stands for Local Area Network. LAN switches work when switches are configured to limit broadcast levels. LAN switches are produced by the company Cisco.
Switches / Bridges and hubs work at data link layer, but there are layer three switches which operate at network layer. Dhruv
No, the Piper Reed series is a work of realistic fiction.

Off and on switches connect to a current. An on switch allows the current to run through an object, essentially "turning it on". Off switches cut of this current.

Water pressure switches work as monitors in a well system. These operate electrical controls and circuits that turn on and off depending on changes in water pressure.
