View Full Version : How much current through a window switch?

09-20-2004, 10:22 PM
Im going to be running a NX 75-150 shot, wet. I am looking at a custom window switch, and I want to know how much current the solenoids will draw.

Any ideas?

The noids shouldnt be drawing any current thru a window switch, the window switch shhould just cut out the power till a certain RPM then switch on a relay that in turn operates the noids. Hope that makes sence to ya.

Yes, this is true.

The window switch grounds between say 3000 and 6000, however, when it is grounded, wont the solenoids put current through the window? If you run too much current, relay goes kaboom...

the only current going through the window switch should be whatever the coil draws on the relay. The relay does the actual switching for the noids...the relay carrys the heavy loads.

In other words...never hook up a noid directly to the window switch.

I think a window switch is good to like 1 amp maybe 2.
The switch in the relay is usually a 30-40 amp.
