Two Positions On and Off

A single-pole rocker switch typically has two positions. When the rocker is pressed on one side, the switch is in the “on” position, allowing current to flow through the circuit.

When pressed on the other side, the switch is in the “off” position, interrupting the flow of current.

SPST VS SPDT

Single Pole Single Throw （SPST）
Single Pole Double Throw （SPDT)

The primary difference between Single Pole Single Throw (SPST) and Single Pole Double Throw (SPDT) switches lies in their configurations and functionalities:

Single Pole Single Throw (SPST):

  1. Configuration:
    • SPST switches have a single set of contacts.
  2. Functionality:
    • The switch can be in either the “on” position (closed contacts) or the “off” position (open contacts).
    • It provides a simple on/off functionality for a single electrical circuit.
    • Commonly used in applications where a straightforward on/off control is sufficient.
  3. Symbol Representation:
    • The symbol for an SPST switch is often represented in circuit diagrams as a simple line with a break (open) or a closed line (closed).
  4. Example:
    • A light switch that turns a light fixture on and off is a common example of an SPST switch.

Single Pole Double Throw (SPDT):

  1. Configuration:
    • SPDT switches have a single set of contacts but provide two different positions for the contacts.
  2. Functionality:
    • The switch can be in one of two positions — either connecting the common terminal to the Normally Open (NO) contact or to the Normally Closed (NC) contact.
    • This switch allows for selecting between two different pathways or functions in a circuit.
  3. Symbol Representation:
    • The symbol for an SPDT switch is often represented in circuit diagrams as a line with a break, indicating the open position, and two connection points (NO and NC).
  4. Example:
    • A changeover switch used in some appliances, allowing the user to choose between different modes or functions, is an example of an SPDT switch.

Comparison:

  • Number of Positions:
    • SPST: Two positions (on and off).
    • SPDT: Two positions with a choice between two different pathways.
  • Functionality:
    • SPST: Provides simple on/off control for a single circuit.
    • SPDT: Allows for selection between two different circuits or functions.
  • Applications:
    • SPST: Commonly used in basic on/off applications, such as light switches.
    • SPDT: Used when a choice between two options or pathways is required, such as in changeover switches.
  • Symbol Representation:
    • SPST: Simple line with a break (open) or a closed line (closed).
    • SPDT: Line with a break, indicating the open position, and two connection points (NO and NC).

In summary, while both SPST and SPDT switches are used to control electrical circuits, SPST provides a simple on/off control, whereas SPDT allows for a choice between two different pathways or functions in a circuit. The choice between them depends on the specific requirements of the application.

Single Pole Type

Single Pole Single Throw （SPST）
Single Pole Single Throw （SPST）

“Single Pole, Single Throw” (SPST) is a term used to describe a basic type of electrical switch. Let’s break down what each part of the term means:

  1. Single Pole (SP):
    • “Single pole” indicates that the switch controls a single electrical circuit. It has only one set of contacts that can be open (off) or closed (on).
  2. Single Throw (ST):
    • “Single throw” refers to the switch’s ability to make or break a single electrical connection. In other words, the switch has only one position for the contacts — it can either be in the “on” position (closed) or the “off” position (open).

Symbol Representation:

  • Two Positions:
    • An SPST switch has two positions: one where the circuit is closed (on) and another where the circuit is open (off).
  • Simple On/Off Functionality:
    • It provides a straightforward on/off control for a single circuit. When the switch is closed (on), current flows through the circuit. When the switch is open (off), the circuit is interrupted, and current stops flowing.
  • Common Uses:
    • SPST switches are commonly used in applications where a simple on/off control is sufficient. This includes basic lighting controls, household appliances, electronic devices, and various electrical systems.
  • Versatility:
    • Due to their simplicity, SPST switches are versatile and can be used in a wide range of settings. They are often found in both residential and industrial applications.
  • Easy to Understand and Install:
    • SPST switches are straightforward and easy to understand. They are typically installed in a standard switch box and can be easily replaced or upgraded.
Symbol Representation:

The symbol for an SPST switch is often represented in circuit diagrams as a simple line with a break, indicating the open position (off), or a closed line, indicating the closed position (on).

Single Pole Double Throw （SPDT)
Single Pole Double Throw （SPDT)

“Single Pole, Double Throw” (SPDT) is a type of electrical switch that controls a single electrical circuit and has two possible positions for the contacts. Let’s break down what each part of the term means:

  1. Single Pole (SP):
    • “Single pole” indicates that the switch controls a single electrical circuit. It has only one set of contacts that can be open (off) or closed (on).
  2. Double Throw (DT):
    • “Double throw” refers to the switch’s ability to make or break two different electrical connections. In other words, the switch has a common terminal and can be in one of two positions, connecting the common terminal to one of two other terminals.

Characteristics of SPDT Switch:

  • Three Terminals:
    • An SPDT switch has three terminals: one common (COM) terminal and two other terminals (often labeled as NO for “Normally Open” and NC for “Normally Closed”).
  • Two Positions:
    • The switch has two possible positions. In one position, the common terminal is connected to the NO terminal (Normally Open), and in the other position, it is connected to the NC terminal (Normally Closed).
  • Versatility:
    • SPDT switches are versatile and find applications where a device needs to be connected to one of two different circuits. The switch can be used to select between two different functions or pathways in a circuit.
  • Common Uses:
    • SPDT switches are commonly used in situations where a choice between two options is required. For example, they are found in changeover switches, selector switches, and certain types of relay circuits.
  • Symbol Representation:
    • The symbol for an SPDT switch is often represented in circuit diagrams as a line with a break, indicating the open position, and two connection points, one on each side.
