Relay switches (also called an electrical relay or an electrical relay switch) use a small amount of power to control a larger source of power connected to electrical devices such as car motors, computers, and lighting installations. A basic relay switch has a control circuit with an electromagnetic coil and a load circuit with contacts and a lever. When current flows into the relay switch, it moves through the coil and a magnetic field is created, which causes the lever in the load circuit to move between contacts, either turning the device on or off. In a normally open (NO) relay switch, when power is supplied to the relay, the load circuit is closed and the power source connected to the relay is turned on. In a normally closed (NC) relay switch, when power is supplied to the relay, the load circuit is open and the power source connected to the relay is turned off. In other types of relay switches, non-moving parts such as transistors or semiconductors can be used as the control circuit to operate the switching mechanism. Relay switches can be controlled with an external switch, such as a light switch, or they can be connected to an automatically switched power source, such as a car ignition. One relay can operate multiple switches, and multiple relays can be operated with a single switch, with each relay operating independently from the other relays in the system.

beast690uk asked How can I tap off a High Voltage, High Speed Electrical Signal?
I have an industrial panel which I believe uses 200-240v, (i've only got pictures). I need to tap of a semi-clean signal which comes through a sensor, I believe this is also cleaned at the panel. I've thought of using a optocoupler to tap of the signal but the highest detection voltage i've seen is 24V. I am also a little worried about using a relay due to the fact that its very high speed and a Relay might be a little noisy.
And got the following answer:
i think your best bet is to use a small isolation transformer. a 240V-to-12V would work fine. I would further recommend a center-tapped xfmr..like 12V-0V-12V. This arrangement could get U a zero-crossing signal, a 1/2 wave rectified signal, an AC signal, or a DC signal. The "isolation" part is the part U should be concened with for safety. TonyB
