On On Switch Diagram. For example, a SPDT switch can be A SPDT toggle switch may be used as a simple on-off switch by connecting to COM and one of the A or B terminals shown in the diagram. This is the very simple circuit diagram of the IR remote control switch.

The schematic diagram symbol for a proximity switch with mechanical contacts is the same as for a mechanical limit switch, except the switch symbol is enclosed by a diamond shape, indicating a powered (active) device: Many proximity switches, though, do not provide "dry contact" outputs.
Relay switch example diagram drawing, vector illustration scheme.
The switch network diagram provides a visual representation of how the switch connects all other devices in a computer network. It visualizes how a network switch connects to other devices within a network. It is also called a changeover switch.
