This used intermittent wiper switch has a two speed wiper function, and when turned counter clockwise, has a rheostat that sets the different delay times. A 1969 switch can be used, but the shaft will be about 3/8" shorter, you may need to use a 1969 metal knob to use in a 1970. Sometimes called interval or delay wipers.
*NOTE* Must be used in conjunction with a Intermittent wiper controller.
