Below is a list of Electrical Switches manufacturers from East Peoria, Illinois. An electrical switch is a device used for changing the configuration of an electrical circuit. Electrical switches are distinguished from each other based on the kinds of circuits to which they are attached as well as the way that they change a circuit’s status. The moving part that applies force to the contacts is called the actuator; it may be a toggle, pushbutton, rocker, dial or other mechanism.
