Isolation Switches: A Quick Guide

Isolation Switches

Handling faulty appliances at home is a difficult and dangerous task. Especially when they need repairments or alterations, our electronic home appliances become extra dangerous. You would not want to risk any chances of getting electrocuted. This is exactly where isolation switches slide in.

Isolation switches are manually operated mechanical switches that keep a circuit apart from devices that require maintenance. For example, the most common use of an isolation switch is in a transformer when the transformer needs repairs or maintenance. An isolation switch blocks the flow of current from the circuit to the device or application.

Basically, an isolator switch or a disconnected, allow sections of electricity or current to pass through or shut down when required. The turning on and shutting down process has to be done manually, unlike circuit breakers.

What Are The Uses For Isolator Switches?

Isolator switches are used in most of the circuits we see in our daily life. All appliances need maintenance at some point of their lifecycle. As we know, electric appliances and devices are very dangerous to be around.

This is why a safety measure has to be taken. An isolator switch serves as a safety device and are now installed in numerous domestic devices and appliances as well as major electrical substations. You can find them in kitchen appliances, electric ovens, electric showers, electric exhaust fans, as well as grids, power lines, etc.

If you wish to shop for a strong isolator switch, opt for the MC4 Connector – PV Connections. Recently, the sales of this one particular product reached an all-time high as customers loved the great results at such an affordable price.

Types Of Isolator Switches.

There are several types of isolator switches available depending on the types of current passing through, where they are positioned, and what task they serve. The main five types of isolator switches can be classified as:

  1. AC isolator switches.
  2. DC isolator switches.
  3. Single break isolation switches.
  4. Double break isolation switches.
  5. Panto graph isolation switches.

 Where Do Isolation Switches Need To Be Located?

Mostly, the location of your isolation switch depends on the situation or circumstances. In some circumstances, you are legally required by the law to place the isolation switch at a specific location.

In both situations, the location of the isolation switch must be:

  • Close to the appliance.

For mechanical maintenance, it is important that the isolator switch is located somewhere near the appliance. For example, when it comes to electric showers, your isolation switch must be near the shower but not close to water or humidity. However, this does not mean the isolation switch must be right next the appliance.

This will make it accessible for untrained hands and can open a lot of room for hazards.

  • And in an accessible place.

Make sure that you place the isolator switch in an accessible place. In case of emergency, you would have to operate it yourself. If the switch is buried behind appliances or hidden away and you are not able to shut it down on time, it could cause equally dangerous accidents.
