A plastic actuator for a toggle switch has a metal rod embedded therein, with the metal surface partially exposed. This surface of the metal rod functions as a bearing surface for a positioning spring as the actuator is flipped back and forth to turn the switch on and off. The use of the metal rod to provide a bearing surface in the toggle actuator substantially reduces wear on the actuator, and thus permits the actuator to be made out of a thermoplastic material rather than a thermoset material, thereby effecting a cost savings.
