Foot pedal.

[Servo]

This is hard to explain.
I already have the foot pedal from that nice guy in china.
But I'm having problems with my foot, so keeping my foot down for the machine to go is painful.
Is there a foot pedal that if you press down then remove ur foot it keeps going, press again for off?

IMO PRECISION CONTROLS - PA20101 - FOOT SWITCH the middle option looks good, so that's just the on off switch, should be easy to wire (I hope). I will test it on the wife first

Thankyou for the help

i forgot what I altered on my switch, but the weight of my foot holds the switch down, and it's only a size 7 foot.

Nev, I wonder if you have time to take a look at the pdf file of that switch. I t came without any instruction. And I don't understand the pdf.

They are not the clearest. So the following is a guess without seeing the switch.

How many connections are there available to you? how are they labelled?
if two, then its probably just in and out
if three, it is probably one in (common?) and then a NO (normally open) and an NC (normally closed). one will become live (switch on) when the pedal is released, the other becomes live when pedal is pressed.
if four I cant guess, i'd need to play with it.

Hi nev, it has four terminals. No marking on them. But I figured they are paired. So I guess I f I wired the two contacts that are floating with the live in live out when the s/w is pressed the saw will start..


Listen for the bang!!

 

[nev]

seeing as it is only one (live) wire being 'broken' by the switch there is not a lot to go bang it will either stay on / off or switch. if it switches when up or down and you want the other try a different terminal. you shouldnt be able to damage either the switch or the machine as you are only making and breaking a contact.

Cheers Nev, wife has just comeback in after trying the s/w and she says it works fine. Now its my turn

:mrgreen: I like your style.

A four wire foot switch will be double pole so it makes/breaks both live and neutral lines

Looking at the info, one side is NO (Normally Open) and the other side is NC (Normally Closed) so that wouldn't work in this case, only one side can be used.
