    Eliminating power switch on ESC

    I'm using a Hobbywing Quicrun 1080 ESC to drove a peristaltic pump for my ballast system, picked for having 100% power for forward and reverse and the pump having a brushed motor. there is one issue i'd like to fix - it has an attached power/program switch that i'd like to eliminate so its on when i power up the system (via remote on/off of the battery. if it had a simple slide switch i'd simply cut it off and ties the wires together - done. the on switch here is a momentary switch and must be hit every time it sees power to turn on the ESC. Has anyone come across something like this? I really don't want to have to open up the WTC to hit one button for the ESC, prefer it be on with the power. Suggestions?

    What happens if you simply press and hold the switch on, then apply power? I’d expect the esc to switch on and stay on until the power is removed, if so simply apply a shunt across the switch or remove it altogether and solder the pair of slotted wires together.

      If you press and hold the switch and then power up nothing the switch is only active when the power is on, you have to wait to power it on. I contacted Hobbywing they say it can't simply be cut and spliced, its a switch activating a soft switch. Beyond that if you hold the switch it puts he ESC into programming mode. Their first response was to add a servo to push the button - not enough room for that. I then thought could i put an output signal off the receiver driven by momentary switch of the transmitter. Another idea would be to replace the momentary switch with a reed switch that could be activated outside the WTC via a magnet. the reed switch is easy but only an option on the surface, using the reciever signal would be the best option if i can make that work.

        Perhaps choose another brand of esc that doesn’t have all this complication.

          I have found the Quicrun ESC's to be very reliable and affordable but i often use the 1060 which doesn't have this issue, but yes you only get 50% in reverse. With the 1080 I think you will have to use another channel to drive a relay to turn it on or whip up a small timing circuit to drive a reed relay which is kind of a PIA. I guess it depends upon the current requirements of your motor but you could use the 1060 with 50% in each direction.

            Thanks for the feedback and suggestions, after trying things with the switch and being told by the manufacture it wouldn't work was googling options and getting more complicated with more to add on and on and on... figure i'm going to have to splice into it and finally cut off the switch to just get access to the wiring. So immediately test what first thought was - to just twist the switch pair together and see what happens. Well POOP, it worked (wasn't supposed to!) so i'm done. Don't you just love when you have to tell suppliers how their product works? Reminds me of calling CAD support at work with a question, they email me a tutorial of a similar subject to which i start laughing "whats so funny?" look at who wrote the tutorial - help desk sent me a tutorial i wrote.
