    New Turn Signal Switch Fixed Steering Column 1970, 1971, and 1972 Mercury Cougar and Ford Mustang


    This offshore switch is assembled with plated steel rivet contacts as opposed to brass rivet contacts like original. Whereas the Torino or Mustang do fine with 2 incandescent rear bulbs the Cougars with 6 bulbs put too much load on the switch and they fail. The only way these switches will hold up in a Cougar is if you convert to LED. We are hoping the supplier will take our advice and correct this problem but until such time we cannot warranty this product. Don Rush 9-11-2017

    1970-72 Drake Turn Signal Switch Brake Circuit Analysis by Vic Varberry

    These reproduction turn signal switches seem to work in Mustangs (2 bulbs)
    but will not handle the extra current load of the Cougar rear tail lights (6 bulbs). 
    The Drake switch has about .3 Ω resistance measured from the (green) brake input
    pin to either the right (orange/blue) or left (green/orange) rear light pins. The Ford 
    switch measures less than .1 Ω. The initial resistance of the Drake switch was as high as .9 Ω.
    The resistance was reduced by actuation of the switch from left to right turns several times
     but stayed around .3 Ω.
    The Drake switch was constructed using plated steel rivet contacts where the Ford switch was
     made using brass rivet contacts. The plating on the Drake switch lugs is shiny like nickel where
     the Ford switch used tin/lead plating. 
    </strong>Circuit resistance, under a 1 lamp load was calculated to be over .2 Ω - much too high. The Ford
    switch was calculated to be .04 Ω.

    Quality Issues

    The old switch has, what looks to me like brass rivets. The new switch uses silvery (zinc plated?) rivets. These rivets appeared to be properly installed, however they did not make a good electrical connection to the ring eyelets, causing heat which had melted the white plastic switch mechanism."

    Why is the door buzzer, buzzing even when the key is removed now???

    I had a broken turn signal switch. I bought this replacement. Now 2 years later I get my car on the road and I notice that when the door is open, the door buzzer, buzzes. Removing the key used to silence the buzzer. So to keep it short, the issue was the turn switch. Well kinda.

    Part of the turn signal switch is a wire that connects to the ignition switch (to detect the key). That wire is held in place by a white plastic piece that fits inside a little pocket in the steering column.

    Look at the contact that is supposed to touch the ignition switch. If it gets bent via shipping or mishandling, it can touch the steering column pocket instead of the ignition switch. Since the steering column is grounded it acts like the key is present even when it isn't. Simply bend the contact back to the center of the pocket and you should be good to go.

    Good Luck,
