pillar drill switch
theconrodkid - 24/3/12 at 06:40 PM

as it was a nice day,i decided to fix my pillar drill,the switch has had it,its a 2 button jobbie with 4 terminals on the back.
could i get away with a simple dpdt toggle switch as mounting a non original switch would be a bit difficult.
also,where would i get such a switch,flea bay only brings up cheapo switches that dont look like they would handle the power

What make is the drill ? It should probably be a 'zero volt' switch, ie if it loose power for any reason it need to be switched ON again. That is, it will now restart when power is restored.
What wattage is the motor? Your local Machine Mart should be able to fix you up with something.

I used a single speed car heater motor rocker switch in my last pillar drill for about 12 years, 1/4 hp motor, in the end it was the table arm which gave out due to mis use.

It is a zero volts switch for good safety reasons

Buy a proper zero volt switch or make your own. If you've got the bits lying around then you need a push to make switch that operates a double pole relay. One pole switches the drill on, while the other parallels the start button, to keep the relay energised. The power to the start button is fed via a push to break switch, so pressing this (or a power failure) de-energises the relay and stops everything. Check you relay rating is sufficient for the motor.

I would have a look at Maplins for a switch, I don't think that a zero volt switch is that important on a home use drilling machine, my old Fobco drill does not have a no volt switch and many older industrial machines didn't.
