Re: DPST required for On button remote switch for Hammer K3?

As far as I know all the switches are 24V, so you don¡¯t need 230V items. They are just NO or NC depending upon whether they are on the run or stop side of the circuit.

Hi all,

first post.? I'm a hobbyist and recently received my K3 winner.? like many of you, crawling over the slider to turn the saw off and on is far from ideal and would like to install a remote switch on the slider.? I've reviewed the various posts and files on the topic (nice work BTW), most of which are pointed at Felder models.? I contacted Felder support, and they were actually quite helpful in providing a wiring diagram (though I did have one in the doc package which came with the machine) and pointing out which part was the power switch, though had to officially tell me not to do it, warranty would be voided, etc, all of which is understandable in the corporate world.? ?The power switch (image of relevant portion below) has a DPST with dual NO contacts for the On button (S1), and a SPST NC contact for the Off button (S0).? does anyone know why they have a DPST for the On button?? from the diagram, it appears that a SPST NO momentary switch would be electrically equivalent.? I assume there can't be much current being switched since it is activating relays.? trying to find a 230 v DPST with dual NO contacts is a bit more challenging (and expensive) than I thought initially, whereas standard SPST NO switches are everywhere and cheap.? ?

any advice will be appreciated.??
