steering column lock - what is this switch?

Hello Group,

I have a "switch" that is located on the left hand side once installed back in the car. I have used a small object to press the "button" on it that I thought would allow it to slide out but nope that is not happening. I think it may be the key buzzer but I can not confirm that. So the question is - Is it the key buzzer switch??

If so I can just reinstall and not have one at this time or do I need to get this switch new? I have the new steering column lock and I am ready to reinstall.

Any help is appreciated. See the pictures.

=)

I have one on my 90 w124 e300d here in the UK,it is a lock out for the auto box shifter.

There are two lockouts on the auto box shifter unit,one is a cable that upon turning the key in the ignition gets pushed and this allows the shifter to operate.
The other is the switch you have and from 1990 in the UK you have to touch the brake pedal to enable the auto box to be taken out of park.

I replaced my ignition with one from an 89 e300d w124 and this did not have the switch fitted ,but the mounting was there for it,it also did not have the threaded mount for the cable to fit into (it had not been drilled and tapped out) so I fitted a nut onto the threaded end of the cable that would otherwise go into the ignition and then fitted a bolt into this nut and screwed it up until the shifter could be released.

Our w124,s in the Uk do not buzz when ignition is put on,all we get that makes a noise is the lights on alarm which screeches like an air raid siren and this will only sound when a door is opened.

On My year and model that is where the Safety Belt Buzzer Goes.

To remove it you need to slide something Flat on each side through those slots of the Switch to depress the sort of Plastic Hooks on each side and also push in the Switch Button.
It looks like the ideal thing would be the flat sections on 2 Bobby Pins with the rounded Plastic Ends removed from the Bobby Pins.
You man need to thin the width of the Bobby Pins.

In the Pic the Arrows point to the parts that need to be depressed in order to get the switch out.

In My case My Steering Colum Lock was no good and I used a Hacksaw to carefully cut of one of the Aluminum lips that held in the Switch.
But, after seeing the Switch and how it is retained I concluded that Bobby Pins would have worked (My Wife does not use Bobby Pins).

In the other Pic circled in red is the area where I cut off one of the Switch Retaining Lips. Note the Switch is already removed.

Thank you. The switch is a pain but now I know how it goes in so I can continue to try to get it out. Now all the new parts are back in but now it is something with the vacuum lines that will not shut the engine off. So not quite done yet but very close. =)

Swap the position of the Vacuum Lines on the Vacuum Valve on the Steering Colum and see if that works. The positions of the Hoses makes a difference.

On Vacuum Line is Brown the other is Brown with a Stripe but I cannot remember the order they go in.

Added: The Brown Line with the Blue Stripe goes on the Bottom Nipple on the Vacuum Valve.
