pillar drill switch repair

[trojan62]

hi folks
hope someone a bit more savy than me can help me out.
i bought an old type pillar drill at the weekend and it works fine, except for one thing.
to turn it on and off, you have to plug in or pull the plug out, it looks like they have joined the wires and by passed the switch.
its not a major problem, but it would be nice if i could sort the switch out.
you can see the pics and hopefully see what i mean.

all help appreciatted.

regards

i am sure that someone have better option...and maybe safer
i guess the switch is faulty

i would get a cheap toggle switch rated at 240v...not a car 12v one

break out the blue wires and connect to switch

just drill a hole in the box somewhere to fit it

my old drill just works off a toggle switch (factory fitted)

or go the whole bit and replace with a new nvr

Hi,

Should be quite a easy repair. The switch isn't broken the whole inside of switch is missing. The box with the green and red buttons with MEM on the front is a contactor and should have a block inside which contains contacts and a coil which will provide overload protection and prevent the machine restarting if the power should be cut and then reappear. I wouldn't attempt to repair whats there but would get a metal clad switch and back box Toolstation list a 10amp switch for under £3.00 which is just what you would need. The glands on the two cables which currently fit into the existing box will fit in the new back box, connect the brown wires to the switch and you should be ready to go. Don't switch the blue wire as suggested as the blue should be neutral which would mean the brown (Live) wire would be unswitched and would mean all of the wiring through the drill would be live up to the switch when the drill is switched off. Although most if not all drills currently seem to have some sort of contactor older drills didn't always do this. My Startrite Mercury Bench Drill originally had a rotary switch which the previous owner replaced with a domestic light switch which has worked well for the 20 years I've had it although its on my Tuit list.
