What is Double Pole Single Throw Switch？
Double Pole Single Throw Switch Symbol
A Double Pole Single Throw (DPST) switch symbol represents a switch that controls two separate circuits simultaneously with a single operation. The symbol typically consists of two parallel lines with breaks in them, indicating the switch’s two poles, and a connecting line that can either complete or break the circuit when the switch is operated. This type of switch is used to turn on or off two different electrical devices or circuits at the same time. It is commonly found in applications where independent control of two circuits from a single switch is necessary, such as in some lighting and power systems.
Double Pole Single Throw Switch Diagram
A DPST switch controls two circuits simultaneously with a single throw of the lever. This switch has four terminals: two input terminals and two output terminals. When the switch is in the “on” position, both circuits are connected and current can flow through both; when in the “off” position, both circuits are disconnected. This is useful for controlling multiple devices or systems from a single switch.
How to Wire a Double Pole Single Throw Switch？
A Double Pole Single Throw (DPST) switch controls two separate circuits simultaneously, with one position being “on” and the other “off.” To wire it, connect each pair of terminals to the respective circuits. Ensure the incoming power lines are connected to one set of terminals (typically labeled “Line”) and the outgoing lines to the other set (labeled “Load”). Secure all connections and insulate as needed.
DPST VS DPDT
A switch with two inputs and two outputs, controlling two separate circuits simultaneously with one action.
A switch with two inputs and four outputs, allowing the connection of two separate circuits to two different circuits, enabling control over four circuits or changing between two outputs for each input.
Various types of switches
A Double Pole Single Throw (DPST) rocker switch is an electrical switch that controls two separate circuits simultaneously with a single action. It has four terminals: two for input and two for output. When the switch is flipped, both circuits are either connected or disconnected at the same time. This type of switch is commonly used for applications requiring the control of multiple circuits from one switch.
A Double Pole Single Throw (DPST) Marine Rocker Switch is a type of switch used in marine applications. It has two input terminals (poles) and can control two separate circuits simultaneously with a single flip (throw). This switch is typically used for controlling devices like lights or pumps in boats, ensuring they operate safely in marine environments. Its rocker design allows for easy operation, even in rough conditions.
A Double Pole Single Throw (DPST) toggle switch is an electrical switch that controls two separate circuits simultaneously with a single flip. It has four terminals: two input and two output. When the switch is flipped, both circuits are either connected or disconnected at the same time. This type of switch is often used to control two devices or to manage a single device with dual power sources.
A Double Pole Single Throw (DPST) micro switch is an electrical switch that can control two separate circuits simultaneously with a single switch action. It has two input terminals and two output terminals, allowing it to connect or disconnect two different lines at once. Typically used for rapid switching in control systems, its compact design and reliability make it suitable for various applications like appliances and industrial equipment.
A Double Pole Single Throw (DPST) push button switch is an electrical switch that controls two separate circuits simultaneously with a single push. It has two input terminals and two output terminals. When pressed, both circuits are either connected or disconnected together. This type of switch is often used for applications requiring the simultaneous control of two different electrical paths.
