+2 anti theft sw

PostPost by: rdssdi » Mon Aug 28, 2006 9:53 pm

I am presently installing the new dash loom.

I need to purchase an anti-theft slide switch. This is attached to the glove
box side. I am a bit confused as to the wiring.

It appears that the horn will be activated when the switch is in one
position and the coil energized in the other position. Is the horn activated when
the ign. is hot and the switch is in "cut off" mode? Is this a form of alarm as
well as an ignition cut off? Can anyone explain?

What type of slide switch does it require? DPST?/on-on?

Thanks

Yes it is a basic alarm as well as a cutoff switch.

Yes, the switch serves as a horn alarm when it is in the "cutoff" position.
In this position, if the ignition switch is turned to start the car the horn
will be activated. It will be activated as long as the ignition switch is
not in the OFF position.

The slide switch is a DPDT/on-on (two position). The ignition circuit is
connected to one pair of poles and a horn ground circuit is connected to the
other pair of poles. In one position, the ignition is closed (on) while the
horn ground is open (off). In the other position, the ignition is open
(off) while the horn ground is closed (on). The horn is energized thru the
accessories contacts on the ignition switch.

A toggle switch could be used in place of the slide switch. I believe the
slide switch was used because it would be less susceptible to inadvertent
switching.

Some people have indicated problems with this switch. It's not uncommon for
it to be eliminated.

Thanks.

That's what I thought. The workshop manual provides a wiring pictorial for
my federal version not a schematic. I have to trace wires as I install the new
harness to be certain I am installing it properly. It helps to understand the
functions.
