being a cheap ass broke biker i came up with an idea for an ignition "switch" for my XR600R

my dad bought 5 magnetic reed switches off ebay, i cadged in and am fitting it in a position of my custom dash but with a washer round it, and i have a neomidium magnet pushed into the end os some tube with a sring n loop to attatch to bars the when placed on the washer activates the reed switch and is strong enough not to fall off nomatter what you do.

my question is would it be better to splice into pulse generator wire or feed to coil. my thoughts if pulse generator bit other may know of a reason why not to,

comments please?

If your choice is a high current load for that reed switch,you better use a relay.....they will not handle high currentv loads without failing,,they`ll overheat..

brian, its 110v 5 amp so i reckon its gonna be ok for 12v electrics........   then again i could be 30 miles away from home giving it some if i am wrong!

110V means nothing,it`s the 5 amp rating that you need to look at closely.......approaching that 5 amp load means a large spark as the reed opens,,,,,,and can actually either weld the 2 reeds together......or distort them from heat......so if i was going to use that type of switch i`d install a relay and have the reed on the pulldown curcuit of the relay.......typically you can easily get relays that only require 200 miliamps on the pulldown side..........and are rated at 20-30 amps on the switched load side.......

with no battery? do people do this? maybe I just need to be edugimicated more?

as the volts decrease, the amps increase, unless im mistaken

Neither. Attach it to the original kill circuit. It will probably test the voltage rating of your reed switch, but the current is low.

Only if watts remain constant. Watts = voltage x amperes. If the resistance of the circuit remains constant, then voltage and current increase or decrease together.
