switch
In electrical engineering, a switch is an electrical component that can disconnect or connect the conducting path in an electrical circuit, interrupting the electric current or diverting it from one conductor to another. The most common type of switch is an electromechanical device consisting of one or more sets of movable electrical contacts connected to external circuits. When a pair of contacts is touching current can pass between them, while when the contacts are separated no current can flow.
Switches are made in many different configurations; they may have multiple sets of contacts controlled by the same knob or actuator, and the contacts may operate simultaneously, sequentially, or alternately. A switch may be operated manually, for example, a light switch or a keyboard button, or may function as a sensing element to sense the position of a machine part, liquid level, pressure, or temperature, such as a thermostat. Many specialized forms exist, such as the toggle switch, rotary switch, mercury switch, push-button switch, reversing switch, relay, and circuit breaker. A common use is control of lighting, where multiple switches may be wired into one circuit to allow convenient control of light fixtures. Switches in high-powered circuits must have special construction to prevent destructive arcing when they are opened.
When the warmer weather arrives and it's time to turn off the central heating what's the best position to leave the radiator TRV's in. Do people leave them in their current position or open them fully or fully closed.
As I found out in an earlier post the radiator valve has a pin in it and I...

Hi all,
I have a Turbomax GB 242E boiler, which provides instant hot water. The way it seems to work is that there is a water switch that detects flow of domestic hot water, which then causes the hot water to be heated (it's a bit more complicated than that but deliberately kept it simple for...

IFLO boiler switch:
I have separate settings for both hot water and heating. However, when I want to set the heating by the thermostat whilst I am away (ie. for frost protection), I seem to have to set both the heating and hot water to "ON" rather than just setting the heating to ON. If I only...
