A good electrical switch should effectively connect and disconnect electrical supply. Single Pole switch disconnects live supply, whilst Double Pole switch disconnects both live and neutral supply. According to testing standard - BS1363, the switch must withstand without excessive wear or other harmful after 15,000 times on/off operations. Assuming one on/off operation every morning, and another on/off operation every night, 15,000 times operations is equivalent to 20years An ASTA approved switch and socket will guarantee this.

As promised to our valuable customers, here is the screenshot for the donation to NHS Charities Together for Jan 2021. Let's pray for the frontline, and wish the corona-virus will be away from UK soon.

   We discovered, in the current UK market, some poor extensions use cables with mixture of aluminum and copper strands. As aluminum has a much lower melting point, once a higher current passed through, excessive heat may be generated and melt the aluminum strands material. After the aluminium strands melted, the cross-sectional area of the cable will decrease, and reduce its electrical rating. The remaining cable strands will heated up more seriously and easily caught fire. A reliable BS extension socket with 3 meter cable, should use at least 1.25mm2 copper strand flexible cables. This cable allows the extension to...

We discovered, some poor extension uses cables to make inner connection with soldering. Once a higher current passed through, each soldering connections will create electrical stress, the higher numbers of the soldering connection stress, the higher risk. Heat will be generated and may melt the inner soldered connection and may cause fire hazards. A good quality extension socket should use solid brass strips for current carrying connection. Since brass has a higher melting point than soldering connection and very good electrical conductivity, it will not melt when a higher current passing through. This makes it a good extension. To find...

Do you know why are the 13A plug pins designed like these? Actually, it is a safety design. When people grip a plug top, slim fingers may accidentally touch the plug pins and causing electric shock. That is why a certified BS 13A Plug has sleeved live and neutral plug pins to prevent this happening. Meanwhile, a certified 13A plug is designed to have a longer Earth pin. This is a safety feature designed to prevent electrocution in that when a plug top is being inserted an Earth connection is made followed by live pins, or withdrawn from socket outlet...
