Review: Connection a bit awkward. - Usual high quality associated with MK switches. Terminals are always a bit awkward to get the wires in but once located in position they are very secure.
Review: Great switch. Solidly built British product made in UK and will last for years - This 20 Amp (4.8 kW) switch is designed for switching heavy loads. I have had 3 installed for over 10 years switching large sotroage heaters on and off regularly and they are as good today as the day I installed them. Just bought another one for a new heater. If anyone is wondering why the neon does not light up, see my drawing and explaination. This switch is designed for all the connections to be used and not as a light switch. Lighting switches only have one wire in and one wire out. There is no way the neon will light up when one end is not connected. If you don't know these things, then you really should call in an electrician. Don't give a product a low rating just because you dont know how to use it.

## Questions & Answers

**Q: Is this switch suitable for controlling a room light**
A: Hi

These switches are generally used to isolate appliances rated at 20amps or less. Say a hob or storage heater.

Technically you could use this to operate a light that is only switched from one point (a one way circuit), say an outdoor light, by using only one side of this double pole switch, but that is an expensive way to switch a light.

If I can help further, please let me know.

Kind regards.

Mike

**Q: What is the difference between this switch and the mk k5423whwhi 20 amp double-pole switch marked water heater? Description looks the same. Thanks**
A: The K5423 WHI is a plain 20a double pole switch.
The K5423WH WHI is the same switch but it has "water heater" printed on the plate front below the switch

**Q: Does it have a flex outlet?**
A: Hello,To confirm, this does have a flex outlet.

**Q: Can the neon be wired to be on all the time?**
A: The neon light is on when the switch is on. Thats the point of it, to remind you the switch is on.
