説明
Restored buildings have a problem the modern hardware shop cannot solve. A flush plastic plate looks wrong on a brick wall, a timber panel or a tiled Victorian hall. The answer is usually the switch that was there in the first place, a ceramic body with a brass lever and a mechanism you can see working.
Ceramic is a better material than it sounds. It does not discolour the way early thermoset plastic did, it takes heat without softening, and its insulation does not depend on a coating staying intact. The brass lever and the screw terminals are the period correct detail, and the action is a plain on and off rather than a dimmed ambiguity.
The rated capacity covers lighting and most single appliances, 20 A at 125 V and 15 A at 250 V, with an electrical life beyond ten thousand operations and a working range from minus 25 to 80 degrees Celsius. Surface mounting suits walls where a back box cannot be buried, and the packs of one, five and ten exist because a restoration rarely needs a single switch.
These are sold in packs because nobody restores a single switch. A five or ten piece set covers a room, a workshop or a rental flat in one order, and the ceramic bodies do not yellow the way early plastic ones did. Surface mounting and a visible brass lever also suit brick, timber and stone far better than a flush plastic plate, which is why they keep reappearing in loft conversions, workshops and old halls.
A switch is the smallest piece of hardware in a room and the one you touch most.

Where These Switches Belong
Restored houses, workshops, loft conversions and timber or brick interiors where a plastic plate would look out of place. Electricians fitting period correct hardware and owners of older properties replacing failed original switches.
Frequently Asked Questions
Q: Can I use it outdoors?
Only under cover and out of driving rain. The ceramic body tolerates temperature and moisture far better than plastic, but the terminals themselves still need a dry enclosure.
Q: Does it work with LED lighting?
Yes. The switch is a mechanical contact, so it does not care what the load is as long as the current stays within the rating.
Q: Will it fit an existing mounting box?
The body mounts on the finished surface rather than into a recessed box, so it can usually go over an existing position once the old plate is removed.
Q: How do I wire it?
One live in and one live out on the two screw terminals, with the circuit isolated first. If you are not certain of the wiring, have an electrician fit it.
Q: Why is the switch rated for two voltages?
The rating is a combination of current and voltage. The contacts carry less current at 250 V than at 125 V, and both figures sit on the label so the limit is clear.
Q: What is the rated capacity?
The switch is rated for 20 A at 125 V and 15 A at 250 V, which covers lighting circuits and most single appliances. Do not use it to switch a high draw load such as a water heater without checking the circuit first.
Q: How many switches does one pack contain?
Ordering options run from a single switch up to a ten piece set. Pick the pack size that matches the number of positions you are replacing.
Q: Is a ceramic switch safe to touch?
Yes. The ceramic body is insulating and the mechanism is earthed through the mount in a correctly wired circuit. Have the circuit isolated and the work done by someone competent.
Q: Which colour should I choose?
White ceramic reads period correct in older houses, black suits industrial and workshop interiors, and the green glaze is the one for a restoration with original tiling.
