FYI, those are short cones.
Also, one switch is the Cherry brand, and the other is a Licon. The Licons are more 'clicky' than the Cherry ones, so they feel different.
Would these due?
What's wrong with Andy's?
Do you want original cones or would black anodized aluminium cones satisfiy you as well
What is the price these are going for at the moment?
There is one running atm. Low cones, though. The cones don't look original to me. I've never seen them with this......don't know how you would call it
And the surface seems different from the ones I know.
The LEDs in those ebay ones (and the others from that seller) are suspiciously bright. It looks like someone replaced the LEDs with ones that are more powerful, and the heat generated started to melt the cones.
Original buttons have a relatively faint glow, as the LEDs are fairly low power.
BTW, I looked at my Q schematic just to verify.
The PL1/PL2 cone buttons are driven by 5V logic and thru a 220R resistor.
(Other Atari boards do the same/similar with 220R or 100R).
I'm sure that Ebay auction, the seller is just biasing the LED directly.
I don't believe the Cherry has integrated bias resistor or not. I'm guessing "not".
No, they don't include the resistor.
However I think if you just hooked them to 5V directly, the LEDs would just blow. I don't think you can make original LEDs look that bright, even with no resistor.
Perhaps you should take one of your original buttons and try it.![]()
LEDs can be biased near their Vf point without a resistor. But in any application, no one would do this.
If the LED has a max Ibias of 25-50mA, and you use a current limited source, then no damage to the device. But in any application, it's easier to use a resistor as the limiting element. (Example, to test an LED, use the DIODE setting on a DVM and it will provide enough limited bias to light up the LED; good to validate which pin is Anode or Cathode, and to indicate that the LED is good and lights up).
LEDs can be biased with DC or with a PWM technique. The latter technique can reduce stress to the device. But in most applications, with DC or PWM, a resistor is still used (as it takes up little space, likely does not dissipate any power, is a good for safety protection and is cheap).
Anyway, if an LED is too bright, just reduce the bias current by using a larger resistor in-series.
