Without the PC power supply box, the computer would not be able to turn on and off
SMPS(switch mode power supply)
To ensure a constant power supply from a light switch, you can connect the switch to a reliable power source, such as a dedicated circuit or a backup power system. Additionally, you can use high-quality wiring and components to prevent interruptions in the power supply. Regular maintenance and inspections can also help ensure a consistent power supply from the light switch.
The line supply connects to the top terminals of the switch and the load connects to the bottom terminals of the switch.
A stop switch is wired in series with the power supply and the load.
When the supply from GEB is cut away, at that time the consumer is required to change over from the main supply to the private generator, so that he cut the supply from mains and switches to Generator with a change over switch.
In North America, the use of a two pole single throw switch is used for this purpose. The reason that a two pole switch is used instead of a single pole switch is that code requires that both legs to the 240 volt load has to be broken so as to isolate the load completely from the supply voltage. If a single pole switch was used in this situation one leg of the 240 volt supply would still be "hot" to ground. Someone that is inexperienced with the system could get a nasty shock by just using the switch to isolate the circuit when working on it instead of using the supply breaker to isolate the circuit. In the UK it is a different scenario as the load across the 240 supply returns to a grounded neutral. In this case just a single pole single throw switch will isolate the circuit.
Yes.
SMPS stands for switched mode power supply
No, it opens the supply voltage and hence the supply current to the load.
it is used to supply power to motherboard and other peripherals
If the hot is connected to the supply and it is turned on and the switch is turned on and the neutral not connected this could be quite true. Connect the neutral to the supply neutral and shut the switch off. Now the only reading that you should get is the hot supply.
In uninterruptible power supply (UPS), it is an electronic switch used to bypass a mechanical switch. Normally used when loads are switched from inverter to mains.Static switch is an automatic switch that can only be activated depending on the condition of the UPS.The following are the conditions wherein the UPS static switch can be activated:1. Overload condition2. Failure of inverter3. Availability of UPS bypass supply but absence of UPS rectifier supply (normal UPS power) that ran out its battery.4. Manual intervention on the UPS that resulted to the activation of static bypass switch.
