Switch Pull Cord Repair / Réparer la corde d’un interrupteur à tirette

Autant que je sache, les radiateurs à quartz à installer au plafond sont très populaires dans les ateliers de menuiserie. Pour ma part, j’en possède trois, achetés un à la fois. J’ai récemment remarqué que la corde de mon plus vieil appareil avait commencé à s’user et que bientôt elle pourrait se séparer au niveau du trou du rivet. Pour prévenir cette cassure j’ai eu l’idée d’enduire la partie usée de colle de menuiserie. Une fois enduite, j’ai utilisé une pince à ressort pour la garder étirée le temps que la colle sèche. Après environ 1/2 heure, lorsque caoutchoutée, j’ai manipulé la colle avec mes doigts pour la mouler aussi douce que possible, pour ensuite réinstaller la pince.

As far as I know, ceiling mounted quartz heaters are very popular in woodworking shops. I own three, purchased one at a time. Recently I noticed that the pull-out cord of the oldest one has started to worn out and soon it will break apart at the rivet through-hole. To prevent the cord from breaking apart I came up with the idea of coating the worn area with carpenter’s glue. When coated, I used a spring clamp to keep it stretched while the glue dries. After about 1/2 hour, when rubberized, I smoothed out the glue with my fingers to mold it as smooth as possible, and set back the clamp.

Le jour suivant, alors que j’ai retiré la pince à ressort, j’ai été ravi de voir que cette surface était maintenant très dure, comme je l’avais prévu, et que cette corde devrait tenir le coup encore plus d’ années que prévu.

The day after, when removing the spring clamp, I was happy to see that the area was very hard, has expected, and this cord should last several more years than expected.

Je vais garder un œil sur les deux autres afin d’appliquer le même traitement avant qu’elles n’aillent trop loin.

I’ll keep an eye on the two remaining ones to apply the same treatment before they get too far.

    ce serait pas plus simple d’y installer une mini poulie?

    • Peut-être plus efficient à long terme, mais certainement pas plus simple ! Je n’ai pas la mini poulie, donc je devrais en chercher et en acquérir une, et je crois que je devrais y investir beaucoup de temps par rapport à ma technique utilisée. Merci quand même pour la suggestion.

      Au plaisir…

    Serge, a good idea using wood glue on it. I hope it holds up for you.

    I have the same one over my workbench and the switch broke a month ago. The switch wouldn’t rotate to the “3” position so only one element would come on. I took it apart (which isn’t easy) and manually turned the switch to get both elements on but have to use the plug to turn it on and off. Yesterday when I plugged it in only one element came on so either the element has burned out or the switch is not making contact again. Unfortunately my cord is in good condition but I can’t use it :).


    • Mark, do you think you’d be able to solder a direct connexion to both elements ? If so, adding a cord switch would complete the job and keep your heater going. Just a thought !


  3. A quick, permanent, and inexpensive (< USD $2) solution would be to install a pull-cord switch that incorporates a metal bushing and a metal chain segment. I installed one in my bathroom ceiling ventilator to enable the fan to be switched off (with the pull cord) while the light remains on. Here is such a switch at "1000bulbs.com"; they're readily available at most hardware stores:

    That’s a good thought. I’ll have a look when I open it up. Right now I have it plugged into an outlet on my bench but it normally plugged into an outlet on the ceiling to keep the cord out of the way. I was thinking of getting a remote switch for it.


    • The remote switch is a good idea too, but perhaps expensive though. Take a look at John’ comment.

      Good luck.

      • Mark Butler says:

        So I went out to the shop today deal with the heater and a tap on the side brought the other element on so I decided to leave it alone. In the meantime I found a remote on Amazon for less than $19 delivered so ordered it.

        I just looked at John’s post and that would have been a good solution but the one shown is only rated for 6 amps. and these heaters are close to 15 amps.


        • A tap on the side ?? Well, your aggressiveness is showing up when things don’t work as expected ! (just kidding) Good move and good result. As they say, if it’s not broken don’t fix it.

          I’ll try to remember to give it a tap when something doesn’t work ! 🙂
