Arcing horns protecting bushings on a distribution transformer. Arcing horns form a spark gap across the insulator with a lower breakdown voltage than the air path along the insulator surface, so an overvoltage will cause the air to break down and the arc to form between the arcing horns, diverting it away from the surface of the insulator.

Steering column. The clockspring is the small black drum with yellow wires at the front end. In vehicle steering systems a clock spring or clockspring is a spiral-wound special rotary electrical conductor which allows a vehicle's steering wheel to turn while still making an electrical connection between the steering wheel airbag and/or the vehicle's horn and other devices and the vehicle's ...
Shown here will be fastened to this recessed, non-metallic box, then a cover plate is installed. This "double gang" (two unit) installation uses non-metallic-sheathed cable and twist-on wire connectors. In electrical wiring, a light switch is a switch most commonly used to operate electric lights, permanently connected equipment, or electrical ...
In 1970, Space Age Electronics introduced the first visual notification appliance, the AV32 light plate (which was installed over an existing horn) and V33 remote light. Meanwhile, in 1976, Wheelock introduced the first horn/strobe notification appliances with its 7000 series. The majority of visual signals throughout the 1970s and 1980s were ...
Thus, an outstretched hand reaching upward and pumping is a signal to the driver of an air horn equipped vehicle, requesting a toot. In modern trucks and buses, the horn is actuated by a button on the steering wheel (just like a normal car horn). Some trucks and buses have both electric and air horn, selectable by a switch on the dashboard.

A push switch (button) is a momentary or non-latching switch which causes a temporary change in the state of an electrical circuit only while the switch is physically actuated. An automatic mechanism (i.e. a spring ) returns the switch to its default position immediately afterwards, restoring the initial circuit condition.
