20 Amp Double Pole Dual Marked SINK BATH Immersion Water Heater Changeover Wall Boiler Button Switch 20A V1218 Twin

Excellent value. Does exactly what I want. I can now easily switch between top and bottom heaters of my hot water storage tank.

It replaced the existing yellowed switch. My only criticism is that poor storage has resulted in signs of corrosion to galvanised plates, steel screws and brass screws - WD40 time!

I used this switch with my Solar i Boost to connect my solar panel output to either the water immersion heater or to a separate oil filled heater. (The i Boost has two outputs but I needed a separate circuit).Item came promptly and seems good quality.Some of the wire fixing screws were slightly corroded, suggesting they had suffered water damage in storage, but this is not a problem.

wanted to switch two emersion heaters easily (full and half tank) this was the perfect switch for the job.Only down side is their is no cable clamps on the switch for strain relief, therefore you need to clamp the immersion heater cables in some other way.

Terrible !Arrived in a shoddy plastic bag for packaging. The switch was dirty, had black and blue marks on it. It lookedsecond hand. The terminal screws on the back are all corroded as if they were in a flood.It also arrived without fixing screws to the back box, which are usually included.I definitely would not recommend this switch. Spend the extra and get something safe. The electric contactsare probably corroded too, which makes this a fire safety hazard.

Unlike the MK switch this does exactly what it says great value for money

This is a really handy switch which enables me to switch between my immersion heater and sink heater. It arrived promptly and was easy to fit. Only downside was some of the terminals and screws had some corrosion on them and needed cleaning up first. Tip: make sure you turn off before switching between units as this may cause arcing!

Good value would buy again
