What is the difference between dynamic and non-dynamic brakes?
Non-dynamic (coast to park) and dynamic braking or parking refer to Windshield Wiper Switches. Your vehicle has either one of the systems for bringing the wipers to the home or parked position.
If you are replacing a switch, you need to know which type it is. Consult your Vehicle Owner's Manual.
For those who need to know how they work, read on...
Essentially, when you turn the wipers Off, they stop when they reach their park position, but they also get retarded electrically to bring the motor to a rapid stop. When you turn the wiper switch Off and the wipers reach the park position (left or right), the armature of the wiper motor is disconnected from the load and immediately connected across ground. The motor then functions as a loaded generator and develops a retarding torque that rapidly stops the motor.
Essentially, when you turn the wipers off, they stop when they reach their park position. When you turn the wiper switch Off the wipers continue to run by a separate set of contacts mounted on the motor, until the wipers reach their park position. At this point the contacts open, removing power, and thereby stopping the wiper motor. If the motor is not in the park position for the wipers, it continues to run until it reaches the park position and the switch opens as before.
What is the difference between an electronic Windshield Wiper Switch and the Microprocessor Windshield Wiper Switch?
Electronic Windshield Wiper Switches are specific to a type of motor (with or without dynamic parking).
Switches designed to work with dynamic park motors: the PARK wire is blue.
75600-01 12V DC, controls two motors,
75602-02 24V DC, controls two motors,
75600-02 12V DC, controls one motor, Packard 6-way,
75600-05 12V DC, controls one motor, Packard 4-way,
75600-07 12V DC, controls one motor.
7-way connector Switches designed to work with non-dynamic park (or coast-to-park) motors: the PARK wire is green.
75601-02, 12V DC, controls two motors, Packard 8-way,
75601-08, same as 75601-02 without knob
Electronic switches have 7 leads ( 2 red leads). Microprocessor based Windshield Wiper Switches can work with both types of motors. They have 6 leads.
75600 12V DC, with 8-way Packard connector.
75600-04 12V DC, with 6 wire leads
75602-04 24V DC, with 6 wire leads.
