Something You Should Know About Flipsky Anti-Spark Switch

Recently we have received many questions from end users asking about our anti-spark switch and button, such as can I use other buttons instead of yours? What kind of buttons will work with your anti-spark switch? How to control two esc with one anti-spark switch/button? We would like to share more information with you about Flipsky anti-spark switch. Let’s get started!


1. There are many different kinds of buttons in the market now , Can I use other buttons for your anti-spark switch? What kinds of buttons will work with your anti-spark switch?

Different switch in market

So how to choose the right one If you only want to change a button?

Firstly, make sure there’s one NO & one NC contacts on the button, because Flipsky anti spark switch are all used NO & NC contacts button.

NO means  Normally open (open circuit, not creating a path for the current)
NC  means  Normally closed (short circuit , creating a path for the current)

Normal open and Normal close button

Secondly, due to different circuit designs of the anti-spark switches, we use different types of button. Therefore, please make sure a self-locking button for Flipsky anti-spark switch pro  and a self-resetting button for Flipsky anti-spark switch smart .

So what’s self-locking button?

Self-locking means that before you press the button, the contact is on the “off”, and after you press the button, the contact will stay on the “on” even when you loose your finger:

And what’s self-resetting?

Self-locking means that before you press the button, the contact is on the “off”, and after you press the button, the contact will on the “on”, but after you loose your finger from button, the contact will go back to “off”:

2. How to exchange the button in Flipsky Anti-spark switch ?

Now throught above item 1, you may get clear what detail type button that used in Flipsky Anti Spark Switch(Pro and Smart) , How to exchange a button if you want to do it? 

(1) Pls choose the same type button as your replacement.

(2) How to connect the replacement button in our Anti spark switch board?

A. Understand the theory firstly : there's + / - / S silk ink in switch PCBA.  and they're corresponding with the 3 pins of your replacement button . See picture

Button Pin

 + means:  NO contact , - means NC contact, S means Common Contact

B. Now we need to find the corresponding function pin in your new replacement button

Firstly, find the common contact pin

a. Don't press the button, measure any two pins, to get the two pins that can create parth for current

b. Press the button, measure any two pins, to get the two pins that can creat parth for current

c. through above two steps, then you will get the common contact pin.

       Secondly, find the Normal Open contact pin.
       Don't press the button, measure the other two pins with the common contact pin
      respectively, if there's open circuit, then this pin is Normal Open (-) , then the other one is
       the Normal Close pin 
      C.  After you clarified the three function pins of the new replacement button. then match                it with our switch correspondingly.
However, kindly remind that the product exchanged components will not be guarranted. We still suggest to use the orignal button.

3.Why do we choose the buttons we’re using right now?

The self-locking button we’re using on Flipsky anti-spark switch pro 280A is from ONPOW, which is with 30 years of history and has gained certification of CCC, CE, UL, VDE, PSE, ISO9001 and so on. It shows on its datasheet that the button mechanical life is up to 100,000 times and electrical life is more than 50,000 times.

The button that we used on Flipsky anti-spark switch smart 280A is manufactured by  HOSONG. They have also passed many certifications: CE, RoHS, IK10, IP67 and so on. And the data sheet shows that they have tested the button 30 times every minute and continued to test it until 500000 times.

Even though the above two buttons are both from companies with good reputation, we still have them tested for three months before we apply them in our products.

4.How can I use only one anti-spark switch/button to control two, three or even four FSESC?

Now let see how to use one switch to control 2pcs FSESC4.12 50A step by step.

  1. Weld the black wires and the red wires together respectively, and add an XT60/90 male connector on the power wires of the 2pcs FSESC4.12 50A


2. Add an XT60/90 female connector on the end of out put of the anti-spark switch, and then connect the twins FSESC4.12 with the switch.


    3. Now, you can use one switch to control two pcs FSESC4.12 50A. 

For the same theory, if you want to use one switch for three or four FSESCs, just weld all the black power wire together, and all the red power wire together respectively, then move on the same process like above description.

5. How to use one anti spark switch to control 2pcs FSESC6.6 with aluminum heatsink, since it has already integrated swtich in the board?

You only need a Y-like button cable. What’s Y-like cable? Well, check the following pictures and you will know what it looks like. Getting a Y-like button cable may require some welding skills.(People who knows little about welding is not recommended to do this) Method’s the same if you want to control three or four FSESC6.6 with only one button.

one button to control 2pcs FSESC6.6

Now you can try to set up the most cost-saving dual vesc 6 by only 2pcs FSESC6.6 simplify version and a Flipsky anti-spark switch pro.

    The antispark of my fsesc dual 6.6+ blew up the very first day along with half of the pcb.
    It was while testing, no load…
    Now the button is useless and the right vesc and remote are not working.
    Waiting for an answer from you…

  • Stefan Sellmair

    i hav a Antispark smart and one Dual FSESC6.6. If i connect both with a Lipo 4S1P 14,8V Akku all is fine, the Button is on and the VESC runs. But if i connect a Lithium-ione 10S5P Akku the VESC start for a moment (2sec.) and go out. The antispark button is out all the time. What can i do?
