2CV wiper switch

Prompted by a question on the 2CVGB forum about wiper switches I had a look at a spare I had from the dashboard I picked up for the LED conversion.

The switch has three connectors on the rear, I’m not sure if there’s a standard reference for them but I’ve labelled them as 1,2 & 3 as shown below:

2CV wiper switch connectors

The connectors on the wiring loom of my 1987 Dolly are as follows:

  1. Blue
  2. White
  3. Black

When the switch is in the ‘on’ position (i.e. depressed) pins 1 & 3 are connected.

When the switch is in the ‘off’ position pins 1 & 2 are connected.  (From the wiring diagram it looks like this is to provide power to the wiper parking mechanism.)
