This is good. These often fail in microwave ovens.

@HaseebElectronics Год назад

exactly it is most common failing component in microwave door interlock

I love that you repair components rather that replace them.

it very easy to remove both point strip out and very easy to remove carbon.

Some technicians advise not to use emery paper to scrub the switch contacts. Special coating on contact points gets scratched so use cleaner solvent & cloth, they say.. True?

@HaseebElectronics Год назад

using zero grade emery sheet (220 or 440 grit) or chamois leather is good. actually we need to remove accumulated material (dust, rust, carbon and oxides due to weather effects, sparking etc) 40 grit: Coarse. 80 grit: Medium. 100 grit: Medium. 120 grit: Fine. 220 grit: Fine. 440 grit: Extra Fine

@paulzac5481 Год назад

use 240 sandpaper grit or just scrape with a knife.

@HaseebElectronics Год назад

perfect knife or thick grains sandpaper makes scratches, which causes sparking and builds carbon deposits quickly

do you have any idea on what can cause that? I have some of these switches in a video game controller. I've used this type of controller for like 20 years w/o problems but since some 3 years ago the switches in it started presenting malfunctioning after 1 day of use or so. Its crazy; it starts double-inputing when the switch is about to disarm. I guess it may have something to do with the power grid from this house Im living now but Im not sure, I have no idea on how to test and find out what is causing these switches malfunctioning.

@HaseebElectronics 4 месяца назад

over-aging is a fact, its contacts get sticky due to some dust rust (spraying contact cleaner can solve this problem) its spring arm's tension becomes weak, and cause bouncing effect while arming or disarming it can be monitored using oscilloscope to check bouncing effect

@gxmcdg 4 месяца назад

@@HaseebElectronicsi guess its something related to the contact area, the arm's tension seems to be just fine. Whenever we use contact cleaner the switch gets back to normal if the switch is brand new, like 1-2 hours of use, but the problem presents itself again after another hour. I really have no idea what causes these hyperfast aging, its looks like magic.

@HaseebElectronics 4 месяца назад

@gxmcdg to overcome this issue 10n to 100n capacitor can be connected in parallel to switch contacts It prevents bouncing effect

@gxmcdg 4 месяца назад

@@HaseebElectronics I understood nothing of that haha, but its not the first time I heard a resistor or capacitor installed somewhere could help dealing with this kind of problem. Would you know what terms I can use to search online in order to learn more about that?

Why no usual Salam from you?

@HaseebElectronics Год назад

some people respond negatively, so i don't want to hurt someone by saying salaam, although it is greeting (best wishes) but some viewers use bad words. so that reason i skip
