20A Double Pole Slim Switch
The DN71324 is a double pole switch produced under the British standard with a maximum of 20A suitable for applications that require total separation of both the live wires and the neutral wires. This DP isolator is a type of water heater switch that has been designed for use in fixed applications where local disconnection is compulsory according to wiring regulations. The DN71324 looks different from conventional 20A isolators as it is characterized by the popular DN71 special baby skin printing finish on a slim panel with dimensions equal to 86mm x 88mm. The main feature of the DN71324 is its choice of materials for panel manufacturing — PC plastic, tempered glass, or brushed metal. The red copper used in the construction of the contact unit has a diameter of 3 mm. The DN71324 is available with two options for middle plate: made from steel or steel plastic wrapping.
We are a manufacturer at the factory level that offers prices which are competitive for wholesale items, allows the execution of an OEM brand on every type of panel and provides a 12-year warranty on the DN71 series range.
20A DP Mechanism— Full Isolation, Premium Aesthetic
This low-profile DP isolator comes equipped with the red copper contact system, comprising a 3.0 mm diameter and 25 mm long salt contact. Designed to endure a maximum of 20 amps, this device measures 88 mm by 86 mm in size. The design features a dual pole, which is significant for electrical systems. The activation of the switch results in both neutral and live disconnections as stipulated by the regulations when it comes to electrical equipment such as water heater circuits, air conditioning units, and fixed units in the kitchen. The usage of a special technology to produce a device makes it easy to remain clean even when used in various high-traffic locations such as kitchens and utility rooms.
Matching the DN71 Series — 20A DP Isolator
The 20A switch with baby skin printing belongs to the DN71 series, which also includes the same dimensions (88×86mm), the same 3 types of panel materials, and the same finishes. The former switches are industrial in appearance; however, this switch has a similar profile and feel to the regular DN71 switches and sockets, eliminating the need for an uncomfortable appearance on the kitchen or airing cupboard wall. You can choose among four colors: White, Gold, Gray, and Black, for consistent performance and aesthetic look on each wall plate.

When to Specify a 20A Double Pole Switch: Water Heaters, Fixed Appliances & Regulatory Compliance
A practical guide to specifying 20A DP isolators for British standard fixed appliance circuits.
Where Is a 20A DP Switch Required?
In accordance with the wiring regulations of the UK and Commonwealth countries, a local 20A DP isolator has been made compulsory for certain fixed appliance circuits. Water heating appliances require dual pole isolation for carrying out maintenance safely – the DN71324 water heater switch combines both features in a compact design. Air conditioning equipment and fixed HVAC devices need a visible disconnection switch that shows the position of the switch. Fixed kitchen appliances – built-in ovens, electric hobs, and extractor hoods must be protected with local DP isolation. Electric circuits do not comply with requirements in this case with the usage of a single pole switch.
20A DP vs 45A DP — Choosing the Correct Current Rating
For circuits up to about 4.8 kW at 240 V, the 20 A double pole switch (DN71324) is suitable – this includes heating systems, air conditioners, and ordinary permanent kitchen appliances. For high-power circuits – like electric cookers, range ovens, and instant showers using up to 11 kW – you will need the 45 A double pole switch. The DN71 range has a 20 A double pole switch in a contemporary baby skin printing design while the R16 series has the 45 A double pole switch which can handle higher current.
Panel Material Selection — PC, Glass, or Aluminum?
PC with baby skin printing: Cost-effective and luxuriously smooth — the preferred option for domestic kitchens and laundry spaces. Tempered Glass with baby skin finish: premium overall visual quality and immeasurable smoothness — preferred option in luxurious residences and high-quality hotels where the DP switch is exposed. Brushed Aluminum with baby skin finish — metallic industrial look with surprising soft feel, ideally suited for modern kitchen and operational areas. All three products are equipped with the same DP mechanism rated at 20A and 12-year warranty.
Frequently Asked Questions
What is a 20A double pole switch used for?
In order to completely isolate both line and neutral in some circuits, a 20A DP switch is used primarily; these circuits include water heaters, immersion heaters, air conditioning units and any fixed kitchen appliances. The DN71324 features the DN71 signature finish of baby skin printing, which is a British standard 20A DP water heater switch. It serves as a local point of complete disconnection which is compliant with UK and Commonwealth wiring regulations for fixed appliances, with loads up to 4.8K at 240V.
What is the difference between a DP switch and a standard light switch?
A regular light switch is a single pole switch which interrupts live wire but never interrupts neutral wire. A double pole switch such as DN71324 interrupts both live and neutral wire at the same time, resulting in complete isolation from electricity. This is a mandatory requirement for water heater circuits along with other fixed appliances in maintenance where technicians need electricity to be fully disconnected before carrying out maintenance works. The DN71324 achieves this using the same thin 88×86mm baby skin print panel as the other devices in the DN71 series.
Can this 20A DP switch be used as a water heater switch?
Definitely, the DN71324 serves the purpose of being a switch for water heater systems and DP isolator that works with fixed devices. This ensures that the device complies with the British wiring regulations, especially with the requirement of having the local double pole isolation for both immersion heaters as well as water heater systems. The 20A rating is suitable for household water heaters and immersion heaters and thus can easily match the design of the DN71 series light switches and outlets.
What panel materials is this 20A DP switch available in?
There are three available front panel variants in the DN71 serie 20A DP switch: “baby skin printing” PC (high degree of clarity, good durability with soft surface), glass (highly shiny, smooth and easy to clean), and aluminum (having metal surface but still very pleasant in touch). All front panel options have the same parameters of 88×86 mm, 20A DP mechanism, and 12 years of guarantee.
