Generally, the ammeter selector switch is a typical 3- position switch. Changeover Switch Ammeter Selector Switches These switches are particularly used in UPS, distribution panels, etc. These switches are applicable in changeover from power supply to generator manual or auto changeover, remote or auto changeover, etc. Voltmeter Selector Changeover SwitchesĬhangeover switches are very helpful in operating two different circuits by using a different no. And also these types of switches also measure voltages in between phases & phase and neutral. Voltmeter selector switches are mainly used for switching in between phases for measurement on a 3-phase system. Isolator Switch Voltmeter Selector Switches Similarly, when the switch knob is turned to BR, then the voltage between BR is shown on the voltmeter. ![]() When the knob of the switch is turned to YB then the voltage between YB is shown on the voltmeter. Once the knob of the switch is turned to the RY position then the voltage between the RY is shown on the voltmeter. Once the power is given to the selector switch, the circuit will be activated. The positive and negative connections of the voltmeter are given to the V+ and V- terminals of the switch. Here the three phasings is given by connecting R, Y, and B terminals of the selector switch to MCQ. In this wiring connection, a voltmeter, a selector switch, and an MCB are used. The connections of this wiring can be done as per the diagram shown above. Voltmeter Selector Switch or Cam Switch Wiring ![]() ![]() For that, a selector switch is used with a voltmeter. This circuit is used to find out the voltage between three phases RY, YB, and BR by using a voltmeter. Here, the type of cam switch used in this circuit is a voltmeter selector switch. The wiring diagram of the cam switch is shown below.
