Cord, foot and inline switches

This site spends a lot of words on lumens, color temperature and CRI. Here is a claim that outranks all of them in practice: a lamp with an awkward switch does not get switched on.

It is a completely mundane observation and it explains a large share of rooms that are darker than their owners intended. A torchiere in the corner with a small twist knob on the pole, behind an armchair, requires standing up, walking round and feeling for it. So it stays off, and the room stays lit by whatever is easier - usually the overhead fixture that everyone says they dislike.

The fix costs a few dollars, and it is worth doing before spending anything on lighting itself.

Work out where the control should be before deciding what it is. The test is simple: sit down where you actually sit, and reach out without looking. Wherever your hand lands is where the switch belongs.

For a table lamp beside a sofa, that is usually the cord at armrest height - an inline switch there is found by touch every time. For a floor lamp beside a reading chair, your foot is already at floor level and finds a foot switch faster than your hand finds anything. For a lamp on the far side of a room from the door, no cord switch helps at all, and the answer is a wireless remote by the door.

Once position is settled, upgrade the function if it is cheap to do so. A Lutron Credenza plug-in dimmer sits between the lamp and the outlet on a 6 ft cord, handles 100W of dimmable LED load, and gives you a control in the same place an inline switch would have gone - except it dims. Given the price difference is small and dimming is the largest quality-of-life improvement available in home lighting, that is usually the right call. The full options are in plug-in dimmers.

For a lamp you also want on a schedule, the Caseta plug-in lamp dimmer does both jobs - it dims by hand and it dims from an app, so the physical control survives a flat phone.

Adding a switch means the cord now has something on it, and where that something sits changes how the cord behaves.

Keep the switch out of the walking route. A foot switch belongs beside a chair, not across the path between a door and a sofa. A switch underfoot in a walkway is both a trip hazard and something that gets operated accidentally.

Do not let the switch take the cord's weight. An inline switch dangling in mid-air puts strain on the cord at both ends of it. Let it rest on something - a table leg, the floor, the back of a shelf.

Route the cord first, then site the switch. The cord run should be the tidy part of the arrangement, and the switch should sit at a natural point along it. Doing it the other way round produces a cord that loops back on itself to reach the switch position. The routing rules are in how to hide a plug-in fixture cord.

Do not cut and splice a cord to fit a switch. Retrofit inline switches that require cutting the cable and clamping conductors are sold widely and are a genuinely poor idea in a rented home or anywhere else - a plug-in dimmer or switch achieves the same thing with no modification to the lamp, no exposed conductors and nothing to explain to a landlord.
