Voltage Selector Switch Circuit

Most electronic circuits contain an on off switch.

Voltage selector switch circuit.

In the 120v only position the power of the two main windings are connected in parallel beyond the circuit breakers and full power can be obtained from the 30a 120v receptacle. Voltmeter selector switch wiring which was about the three phase voltage measuring and in which we did not talk about the neutral connection. One way to classify switches is by the connections they make. In this post i also write about voltmeter selector switch connection wiring but in the last time i talk and publish diagram about the 3 phase and in this post you will learn how to measure 3 phase 4 wire system voltage using a voltmeter selector switch.

If you were under the impression that switches simply turn circuits on and off. Simply defined a switch is a mechanical device used to open and close a circuit. If incoming power needs to be controlled an easy way to do that is with a switch. 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.

Interpower switches and voltage selector switches. 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.
