The two rotary switches are funny items.

1. Dimmer Switch - I've never driven a british car that needed the dash lights "dimmed", same switch in different forms is available on all the british cars.

This has to be the switch that spawned the joke about Lucas switches, OFF-DIM-FLICKER, they all seem to work this way. Some are OFF-FLICKER-FLICKER positions and a rare few OFF-FLICKER-SMOKE...

Most are engineered with dual tabs on one side just for bypassing them... this will "brighten" the lights and thus you can ALMOST see the gauges.


2. Wiper Switch - I've never seen the "ideal" one available, i.e. one with a park position to correctly operate the available later type Lucas wiper motors.

My theory is the rotory switch was ONLY used on the older style motor, 50's style wiring and didn't need the "off" hot parking circuit.

Anyone know?

A special toggle switch was used with the later wiper motor and is still available.

Just put the rotory HNP knob on this wiper switch... and put it in "N". If it rains, you'll be prepared!
