Electrical Schematic Key Switch Symbols Pdf

Electrical schematic key switch symbols are used to represent the different types of key switches in an electrical circuit. These symbols are standardized so that engineers and technicians can easily understand the function of a key switch in a circuit.

There are two main types of key switches: momentary and toggle. Momentary key switches are activated when the key is pressed and then released. Toggle key switches remain in the activated position until the key is pressed again.

The most common type of key switch symbol is the rectangular symbol with a circle in the center. This symbol represents a momentary key switch. The circle represents the contact that is made when the key is pressed.

The symbol for a toggle key switch is similar to the symbol for a momentary key switch, but with a small triangle at the top of the circle. The triangle represents the movable contact that makes and breaks the circuit when the key is toggled.

In addition to the basic symbols for momentary and toggle key switches, there are also symbols for other types of key switches, such as push-button switches, rocker switches, and slide switches. These symbols are all standardized and can be found in electrical schematics.

Here is a table of the most common electrical schematic key switch symbols:
