20A Double Pole Switch with Neon for Complete Isolation of High-Power Appliances
The R30324 is a 20A dual-pole switch designed for use on circuits that require full disconnection of both the live and neutral conductors from the power supply. This dual-pole (DP) switch is rated to operate at 250V and will simultaneously break both conductors when switched to the “OFF” position. This is an important safety feature for fixed appliances such as water heaters and air conditioning units, which require the assurance that both power conductors have been interrupted before performing maintenance or during a power failure.
The built-in neon indicator allows electricians and end users to easily identify that the circuit is powered (live) at a glance, as it provides a visual indication based on the load condition. This is in addition to the opportunity for the end user to confirm that the appliance circuit is receiving power through the integrated neon indicator. The switch is packaged in the 86×86mm R30 PC wall switch panel, available in four colors, and comes with a 12-year warranty. This dual-pole switch integrates high-current isolation into the same clean aesthetic of the rest of the R30 series of wall switches.
True Dual Pole Isolation — Disconnection of the Live and Neutral Conductors: Unlike a single-pole switch that only disconnects (breaks) the live conductor, with a DP switch, both the live and neutral conductors are disconnected on a 20A circuit at the same time. This is a requirement of many wiring regulations concerning fixed appliance circuits, and is recommended practice where complete electrical separation is required for maintenance purposes and for the purpose of keeping the appliance(s) safe for use in the event of an emergency.
20A Rating with Built-in Neon Visual Indicator: The 20A/250V rating of the switch is capable of handling high-current resistive and/or inductive loads without being derated. The neon light is connected on the load side, and illuminates when the circuit is powered (live), providing an instant visual indication that the appliance circuit is powered. Without power to this DP switch, your neon bulb will not illuminate, nor will the equipment connected to it function.
Red Copper & Silver Contacts — Created for 20A Switching
Red Copper & Silver Contacts — Created for a durable product that provides a low level of voltage drop at the contact point, while allowing for a robust, dependable mechanism operation with a long service life (up to 10,000 cycles).
The internally arranged bar-type system made of red copper stamped parts and bushings are used to support the full 20A load on both poles of the switch. The contact points on each of the two poles consist of Φ3.5mm × 0.35mm silver alloy contacts which provide for arc suppression during both break and make of high-current applications. A robust design for both the front panel and base use made of high-bright high-impact PC material, while an iron center plate provides added structural integrity to the assembly to create a solid feel with the heavier internal mechanism.

Where to Specify a 20A Dual Pole Switch
Application notes for electricians and contractors specifying a DP switch for fixed appliance isolation.
Application Use Cases
For residential water heaters and immersion heaters, this 20A dual pole switch provides the mandatory local isolation required by UK and Commonwealth wiring regulations. In kitchens, it serves as a visible isolator for built‑in ovens, electric hobs, and cooker hoods. For commercial air conditioning units and fixed HVAC equipment, the neon indicator allows maintenance personnel to confirm the circuit is dead before servicing. Unlike a standard single pole wall switch, this DP switch ensures no potential remains on the neutral side of the circuit.
Double Pole vs Single Pole — When Full Isolation is Required
A standard single pole wall switch only breaks the live conductor — the neutral remains connected. This is acceptable for general lighting circuits. A dual pole switch breaks both live and neutral simultaneously, providing complete electrical separation. This DP switch is legally required or strongly recommended for circuits supplying fixed appliances, particularly in locations where water is present or where maintenance personnel need full isolation before working on equipment.
Installation Note
The R30324 mounts into a standard 86×86mm British back box. Terminals are clearly marked for incoming and outgoing live and neutral connections, with a separate terminal for the earth continuity. The neon indicator is wired internally across the load side and requires no extra wiring. Due to the 20A rating, ensure that the supply cable is appropriately sized and that all connections are torqued securely.
Frequently Asked Questions
What is a dual pole switch?
A dual pole switch, often abbreviated as DP switch, controls two conductors simultaneously — typically both live and neutral — from a single wall plate. Unlike a standard single pole switch that only breaks the live wire, this dual pole switch provides complete circuit isolation. The R30324 is a 20A dual pole switch with a neon indicator, designed for fixed appliances where full disconnection is required for safety.
How to know if a switch is single or dual pole?
Check the number of terminals. A single pole wall switch has two main terminals. A dual pole switch like the R30324 has four terminals — two for the live conductors and two for the neutral conductors. The presence of a neon indicator alone does not indicate dual pole; many single pole switches also have neons. A 20A current rating is often another sign, as DP switches are commonly specified for higher‑current appliance circuits.
What is a DP switch used for?
A DP switch is used for circuits where complete electrical isolation of both live and neutral is required. Common applications include water heaters, immersion heaters, air conditioning units, electric ovens, and fixed kitchen appliances. Wiring regulations in many countries mandate a dual pole isolator for these circuits. The R30324 20A neon switch is built specifically for this function.
Is a DP switch the same as a double pole toggle switch?
Yes, a DP switch is the same as a double pole switch. “Toggle” simply refers to the rocker actuator style. The R30324 uses a rocker‑style actuator, and its defining characteristic is the dual pole switching mechanism that simultaneously breaks both live and neutral conductors. This 20A DP switch is suitable for high‑current appliance circuits, unlike lighter‑duty toggle switches intended only for lighting.
