Easy Killswitch

Introduction: Easy Killswitch

This killswitch is easy to make and only costs $9.27!
It can be uses on any thing that uses a 1/4 phone jack.

What a kill switch does for those who do not know is when pressed it kills the sound. the button on the top is a momentary on switch that when pushed reroutes the signal to the ground thus shutting off the sound for as long as you hold down the button. By pressing the butting rapidly you can create some cool studdering effects.

I'm going to show you two ways to make the killswitch. One way is just a killswitch and the other has a added rocker switch. If you record guitar or and thing else you can flip the rocker switch over(killing the noise)so there is complete silence well you wait for you part to come up then you can flip it off to bring the sound back. This makes it so when you are waiting there is not the sound of you hitting the strings or any thing else.

If any thing does not make sence to you feel free to PM me with a question.

Credit for the idea to make a kill switch goes to Super Cameraman though I did modify it a bit

Please leave a comment and rate my Instructable I like to know what need to be improved/changed.

Step 1: Materals

Stuff You Need:
Drill with bits
Wire
Soldering iron
solder
2 1/4 audio jacks
a momentary switch(push to turn on)
some sort of box to hold it all

Stuff I Bought:
1/4" Stereo Panel-Mount Audio Jack (2-Pack) $3.99
SPST"soft-touch"momentary pushbutton switch $2.99
3x2x1" Project Enclosure $2.29
rocker switch(optionanal) $2.99
total #1 $9.97
total #2(with rocker) $12.96

Step 2: Drilling

NOTE from here on there will be two sets of steps one for a progect with rocker switch and one with out.

With out rocker switch(pic one)

1 Drill 2 holes (one on either side)for the jacks.

2 Drill one hole in the center of the cover for the momentary
switch

With rocker switch(pic two)

1 Drill 2 holes (one on either side)for the jacks.

2 Drill one hole in the center of the cover for the momentary
switch

3 drill one hole in the front for the rocker switch.

Step 3: Wiring and Sodering

With out the rocker switch.(pic one)

1 Install the switch in its hole, tighten the nut on the momentary switch.

2 Solder a wire connecting the two short posts on the jacks
together

3 solder a wire go from the long jack post to the other long jack post

4 solder wire go from the amp side jack(left)long post to the momentary switch and a wire go from the momentary switch to the shoter post on the amp side jack.

5 insert the two jacks in there holes and tighten the nut on(make sure the long post is not touching the bottem of the box because when you plug in you will bend the jack.)


With Rocker switch(pic two and three)

1 Install the swiches in their holes, tighten the nut on the momentary switch and glue in the rocker switch if you can't get the nut on.

2 Solder a wire connecting the two short posts on the jacks
together

3 solder a wire go from the long jack post to the other long jack post

4 solder wire go from the amp side jack(left)long post to the momentary switch and a wire go from the momentary switch to the shoter post on the amp side jack.

5 solder wire go from the amp side jack(left)long post to the rocker switch and a wire go from the rocker switch to the shoter post on the amp side jack.

6 insert the two jacks in there holes and tighten the nut on(make sure the long post is not touching the bottem of the box because when you plug in you will bend the jack.)

Step 4: Mounting and Playing

To finish the project up lable the sides some how so you know where the guitar plugs in and where the amp plugs in.

You can mount this killswitch any where and you can take it off if you don't need it. I keep mine velcroed to my pedal board but you can mount it to your guitar or keyboard. Jest about any thing that uses a 1/4 phone jack you can use this killswitch.

I hope you have a blast making all kinds of weird noises with this and I would love to hear and see pictures about how it came out. If you liked my instructable please rate it.

    I made one last nite,Before I saw this....Its the same W/O the rocker, but I used Command picture hanging strips to mount it on my guitar. That way I can remove the strip and not have to scrub adhesive if my guitar if I ever want to remove it.

    good post! will 1/4" Mono Jacks work? Any difference? Also, does it matter if the Mono Jacks are open or closed circuit??

    What gauge wire should I use?

    Fantastical! My bf's a guitarist, and for his bday my plan is to connect two homemade loopers (outlined in this instructable), each with their own on/offs, to your kill switch to overall make a two channel looper. I'm pretty excited about it (and the fact that it automatically means he's gunna have to step it up for my bday! ;D) and I'll report back if it's successful! Whee! =D

     can i just twist instead of solder?..and any ideas on how 2 add 2 LEDs 2 the box..1 4 rocker and 1 4 button?????

    1 reply

    u cant add leds because there is no power to power them, unless u ran external power... but you could twist it, but its better to solder....

    hey man, does the colour of the wire matter? are their differences in the wires? i'm a dummie, but i'm pretty good @ soldering, so the wires are the only thing i'm worried about! (btw i don't want comments like "you should let someone with knowledge do it for you!")

    color is personal preference and to keep track of what gets wired where

    the color of the wire does not matter at all.some wires have lots of small strands, and other have one thick peice, itl be best to use the stranded

    Wire color doesn't matter. It's all the same wire, it's just colored so you can easily keep track of which wire is which

    looks like a '61 remake..

    Fixed it wired it wrong!

     same here! any ideas on what i did? i checked all the soldering it looks solid.. maybe i looked at the schematic wrong..

    What happended to me was i wired one sides Sleeve(ground) to the other sides tip(the place that your guitar signal comes from). once reversed(sleeve to sleeve, tip to tip.)  the buzz goes away.

    PLEASE SOMEONE HELP!!!! i made it and it works but there is a very annoying buzzing sound that happens when i plug it in. Is there a way to fix it

     does the switch have to be normally open, or normaly closed? please answer.
