            <title>[MC-4173] Buttons occasionally output too short pulse</title>
                <link>https://bugs.mojang.com/browse/MC-4173</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;Sometimes when activating a wooden or stone button, there is a possibility that the button activates not for 10 or 15 ticks as it should, but a much shorter amount of time. sometimes only a few ticks long.&lt;/p&gt;

&lt;p&gt;happens completely randomly in survival and creative mode.&lt;/p&gt;</description>

I&apos;m coming here to confirm that this annoying bug still exists in stable release 1.5.2. It&apos;s a semi-rare, randomly-occurring bug, and I&apos;ve noticed it in some form or another ever since buttons were initially implemented (sometime in Alpha/Beta).&lt;/p&gt;

&lt;p&gt;I think the only way of fixing this right now is to place a repeater facing away from the adjacent block where the button is placed, to help sustain the pulse. Although this method won&apos;t be practical for things like small button-operated iron doors, for example.&lt;/p&gt;

SMP: A button in a minecart train station - which was functioning since ever - gave once a too short impulse.&lt;/p&gt;</comment>
                            <comment id="29470" author="jumjummington" created="Wed, 19 Dec 2012 13:50:30 +0100"  >&lt;p&gt;I&apos;ve seen this in a circuit I currently use. This is using a wooden button, however I have also seen this occur with a stone button. The sounds line up with the shorter pulse as well, playing the second &quot;click&quot; sound more quickly than usual. As for the length, hard to say, maybe describing the circuit path would be helpful? The signal travels through 5 meters of redstone wiring to activate a dispenser, then through a repeater set to a 3 tick delay to a falling edge detector using a repeater lock which powers the dispenser when the pulse ends. The pulse generated normally from either a stone or wooden button is long enough to activate the dispenser twice with that circuit. The shortened pulse is enough to make it through the 3 tick delay repeater and &quot;charge&quot; the falling edge detector but the pulse doesn&apos;t stay on long enough for the falling edge to activate the dispenser a second time. This has happened twice in the past 100 uses of the circuit.&lt;/p&gt;</comment>

Happens on smp, too, and it&apos;s not a client-side problem because a minecart moved halfway through a powered rail with this shorter pulse.&lt;/p&gt;</comment>
