Kill Switch replacement?

[mikerecike]

 

Echo with a hole where the kill switch should be. Not too savvy re: electrics (like most things until I've done it a few times). Bought these 3 switches - some say 12v on side - problem? p has 2 terminals at back, t has 2 and g has 3 - not sure which to use and what's the general principle here? i.e what wire/s should be going where.

 

or even whether these type of switches will work at all - what do you do?

 

Any help appreciated folks

P has 2 terminals because it is designed to interrupt a circuit

 

G and T have three wires because they are illuminated

Most saws stop by shorting the ignition circuit out, you could probably make P work but I would need to see the saw(?) to be sure.

The ones with three terminals are for a little light that illuminates when the switch is in use.

 

P would work ok. It's easier to put a voltage meter on it to see witch way is on or off before fitting it to saw so you get the terminals round the right way before hand. Just makes it easier than getting the wrong way round and having to take it apart again to swap them.

 

Depending on how much space is behind the switch determines if the switch will fit.

 

Don't worry about the voltage of the switch for this application it really doesn't matter.

My Echo CS-8000 has the same problem, I used a standard 2 way switch from Maplin , seems to work as well as an original.

P would be the one I would use .

Thanks Rich and Tree - really helpful and appreciated - I'll give it a whirl

all the best

Some are single pole single throw, some are double pole single throw, some are normally open, some are normally closed, some handle high current, some handle low current, some need a high operating force and some have a low operating force, some are lit, some aren't, some have silver, gold, plattinum or alloy contacts, some are rockers and some are slide contacts, some are IP rated and some are not.

 

Anyone still awake:blushing:

 

Basically you are connecting from the coil to earth, in operation the switch will be open and when the saw is turned off, the switch is closed - this is not typical of the majority of switches.

 

Husqvarnas use a slide type switch which is good as the contacts are cleaned by the operation of the switch each time it has used.

 

I have replaced Husky switches with rocker type.

Oh yawn. You finished. :lol::lol:

 

Can tell what you do for a living.

Thanks Spud - and yes - this is one of the things in my life that will keep me wide awake - I can't get enough. Cheers.

ok spud i need a switch for a glow plug tester round momentary type

4 terminals 1 set n/c 1 set n/o 8 amp 12v any ideas?
