Most electronic circuits contain an on off switch.
Voltage selector switch circuit.
Voltmeter selector switch wiring which was about the three phase voltage measuring and in which we did not talk about the neutral connection.
Opening a circuit which turns a device off is attained by interrupting a connection in the circuit.
If incoming power needs to be controlled an easy way to do that is with a switch.
Schneider electric maintained selector switch 3 position knob 2no 10a 600v xb4 series.
If you were under the impression that switches simply turn circuits on and off.
The voltage selector switch changes the two main windings from a parallel connection for 120v only to a series connection for the 120 240v position.
Simply defined a switch is a mechanical device used to open and close a circuit.
Interpower switches and voltage selector switches.
On the other hand if the power supply has a voltage selector switch based on the delon circuit for 115 230 v computer atx power supplies typically are in this category the selector switch would have to be put in the 230 v position and the required voltage would be 325 vdc 230 2.
In addition to the on off switch many circuits contain switches that control how the circuit works or activate different features of the circuit.
