In our step by step electrical wiring installation tutorials series, We will show how to wire and connect single phase and three phase automatic and manual changeover and transfer switches to the home distribution board to use the backup power supply such us batteries power with UPS and inverters or generator power in case of emergency breakdown and power outage.

The following fig 1 shows different single phase and three phase connections for manual and automatic changeover and transfer switches. Lets explain one by one in detail as follow. Click image to enlarge.

In fig 2, different connection and wiring diagrams are shown for a two pole, single phase manual changeover switch. The upper portion of the changeover switch is directly connected to the main power supply while the lower first and right connections slots are connected to the backup power supply like generator or inverter.

The left side of lower slots are connected to the main board as load.

This way, power supply will continue to the load points through the inverter or generator. Related posts:. If you are tired of manual operation of changeover switches, ATS is the best alternative to use then. In case when utility power is not available, the ATS will transfer the switching position to the Inverter, hence electrical appliances will be still in operation mode without interruption through the stored power in the batteries.

Related Tutorials:. Fig 4 shows that how to wire a four poles, three phase manual changeover switch to the main distribution board. This is the same connection as we discussed above for single phase wiring expect that there are three phase wires instead of line and neutral. The left side four slots connection points are connected to the load then. Since the operation is manual, You have to change the changeover lever to the appropriate position manually to restore the power i.

Related Posts:. Fig 5 shows 4-Poles, 3-Phase automatic transfer switch ATS connection to the main distribution board. All the wiring connections are same as above for manual operation of three phase changeover switch but the switching operation is automatic. In our previous post, we have shown in very details that how to connect a portable generator to the home supply with automatic and manual transfer switches. It is also shows the working and operation for different changeover switches wiring connections like, single phase manual changeover switch with generator, three phase manual transfer switch connection with generator as well as single phase and three phase automatic transfer switches connections to the 1 and 3 phase generators and main fuse board.

Deepak Deepak 1 1 silver badge 8 8 bronze badges. A selector switch has no default position. That is their resting, non-activated or default condition. They aren't whatever you mean by a 'selector switch'. To me a selector switch might be a rotary switch that always has one way connected.

Some actuator presumably which is not shown. The 2 contacts of SS1 are still 'normally open' until selected.

Special Switches multiway, tilt, reed etc. The following terms are used to identify different types of standard switches :. A simple on-off switch has one set of contacts, single poleand one switching position which conducts, single throw.

A simple push-switch, such as one for a doorbell, has one set of contacts and the on position is only momentary, as soon as you release the switch it goes back to off. This action is called push-to-make push to close contacts. Switch contacts are rated with a maximum voltage and current, and there may be different ratings for AC and DC.

The AC values are higher because the current falls to zero many times each second and an arc is less likely to form across the switch contacts. For low voltage electronics projects the voltage rating will not matter, but you may need to check the current rating. The maximum current is less for inductive loads coils and motors because they cause more sparking at the contacts when switched off.

This type can be used to switch the power supply to a circuit. The photograph shows a SPST toggle switch. When used with mains electricity this type of switch must be in the live wire, but it is better to use a DPST switch to isolate both live and neutral.

This is the standard doorbell switch. Rapid Electronics: push-to-make switch. Rapid Electronics: push-to-break switch. This switch can be on in both positions, switching on a separate device in each case.

It is also called a changeover switch. For example, a SPDT switch can be used to switch on a red lamp in one position and a green lamp in the other position. A and B are interchangeable so switches are usually not labelled.

This is a special version of the standard SPDT switch shown above. It has a third switching position in the centre which is off. The brackets are used to show the momentary action. A pair of on-off switches which operate together shown by the dotted line in the circuit symbol. A DPST switch is often used for mains electricity because it switches both the live and neutral connections.

A pair of on-on switches which operate together shown by the dotted line in the circuit symbol. This is a special version of the standard DPDT switch shown above. This can be useful for motor control because you have forward, off and reverse positions. This looks like a momentary action push switch but it is a standard SPST on-off switch: push once to switch on, push again to switch off.Switch Contacts - pole, throw etc.

Special Switches - multiway, key, tilt, reed etc. Circuit symbol for a simple on-off switch. For low voltage electronics projects the voltage rating will not matter, but you may need to check the current rating. The maximum current is less for inductive loads coils and motors because they cause more sparking at the contacts when switched off.

A simple on-off switch. This type can be used to switch the power supply to a circuit. When used with mains electricity this type of switch must be in the live wire, but it is better to use a DPST switch to isolate both live and neutral. A push-to-make switch returns to its normally open off position when you release the button, this is shown by the brackets around ON.

This is the standard doorbell switch. A push-to-break switch returns to its normally closed on position when you release the button. This switch can be on in both positions, switching on a separate device in each case. It is often called a changeover switch. For example, a SPDT switch can be used to switch on a red lamp in one position and a vmix scoreboard plugin lamp in the other position. A and B are interchangeable so switches are usually not labelled.

It has a third switching position in the centre which is off. SPDT rocker switch. A pair of on-off switches which operate together shown by the dotted line in the circuit symbol. A DPST switch is often used to switch mains electricity because it can isolate both the live and neutral connections. A pair of on-on switches which operate together shown by the dotted line in the circuit symbol.

A DPDT switch can be wired up as a reversing switch for a motor as shown in the diagram. This can be very useful for motor control because you have forward, off and reverse positions. This looks like a momentary action push switch but it is a standard on-off switch: push once to switch on, push again to switch off.

This is called a latching action. Microswitches are designed to switch fully open or closed in response to small movements. They are available with levers and rollers attached. Tilt switches contain a conductive liquid and when tilted this bridges the contacts inside, closing the switch. They can be used as a sensor to detect the position of an object.

Some tilt switches contain mercury which is poisonous. The contacts of a reed switch are closed by bringing a small magnet near the switch. They are used in security circuits, for example to check that doors are closed.

Warning: reed switches have a glass body which is easily broken! For advice on handling please see the Electronics in Meccano website. This is a set of miniature SPST on-off switches, the example shown has 8 switches.
