Switching functions such as for windshield wiper control in a vehicle are remotely controlled by a manually positioned optical selector connected through a fiber optic conductor to an electro-optic transceiver. The transceiver provides a light source for illuminating the light conductor and the selector controls the positions of color coated mirrors which are selectively positioned to reflect color coded light via the light conductor to the transceiver which analyzes the modified light spectrum. A logic circuit responsive to the transceiver output controls actuators according to the selected switch function.
