Product Information
Full details
The SMJ Electrical 20A DP Switch is designed for homeowners and electricians needing a reliable way to control a single circuit with enhanced visibility. Its key benefit is the integrated neon indicator, which clearly shows when the circuit is live, offering an extra layer of safety and operational awareness. A potential caveat is its focus on single-circuit control, making it unsuitable for multi-circuit applications.

FAQs
What is a double pole (DP) switch?
A double pole switch disconnects both the live and neutral conductors of a circuit simultaneously, providing a more complete isolation than a single pole switch.
Can this switch be used for outdoor applications?
No, this switch is rated for internal use only and should not be exposed to moisture or outdoor elements.
What is the maximum current rating for this switch?
The switch is rated for a maximum of 20 Amps.
Does the neon indicator consume significant power?
The neon indicator uses a very small amount of power when illuminated, designed to be negligible in terms of energy consumption.
How do I reset the switch if it trips?
This switch does not have a reset function like a circuit breaker. If a circuit trips, you would typically address the fault at the consumer unit or check the connected appliance.
Is this switch suitable for controlling lighting circuits?
While it can control lighting, it is more commonly used for higher-load circuits or where a clear visual indicator of power is desired, such as for heating appliances.
Troubleshooting
Neon indicator light not illuminating
Ensure the circuit is switched on at the consumer unit and the switch itself is in the 'on' position. Verify wiring connections for both live and neutral at the switch terminals.
Switch feels stiff or difficult to operate
Check for any obstructions around the switch plate or within the wall box. Ensure the switch is correctly mounted and not overtightened against the wall.
Intermittent power to the controlled circuit
Check the wiring connections at the switch and at the appliance/circuit breaker for tightness. Ensure the circuit load does not exceed the 20A rating.
Pros and Cons
Pros
- Provides clear visual feedback on circuit status with the neon indicator.
- Double pole switching enhances safety by isolating both live and neutral.
- Durable matt white finish for a discreet and professional look.
- Suitable for direct control of high-demand circuits up to 20A.
- Includes fixings for a convenient installation process.
Cons
- Only controls a single circuit, limiting its application in complex systems.
- Requires basic electrical knowledge for safe installation.
- Neon indicator might not be suitable for all aesthetic preferences or environments.
- Primarily designed for internal use only.
Setup, Compatibility & Care
Setup: Ensure the main power supply is switched off at the consumer unit before attempting installation. Connect the live and neutral wires to the appropriate terminals for the circuit you wish to control. Refer to the product manual or consult a qualified electrician if unsure. The switch is designed for internal use with standard UK 240V mains power.
Compatibility: This switch is designed for controlling a single 20A circuit on a 240V system. It is compatible with standard UK single-gang wall boxes.
Care: To clean, always switch off the power supply at the mains. Wipe the switch with a soft, dry or slightly damp cloth. Avoid using abrasive cleaners or solvents, as these can damage the matt white finish.
