I have one in my wiper door...and a shematic with 3 relays to run it with intermittant wiper operation....

use magnetic Radio Shack burglar alarm switches for sensors....:bounce:

SpalUSA.com sells linear actuators. Some even have a programmable controller.

Find someone that resells them. I just went to their site and searched for linear actuators and got an "access forbidden" message :confused2:! How lame.
