Overview of Wiring Diagrams for Pressure Switches

Wiring diagrams for pressure switches provide visual instructions on how to connect the switch to an electrical circuit. They are essential for ensuring the safe and proper operation of the pressure switch, as well as for troubleshooting any issues that may arise.

There are several different types of wiring diagrams used for pressure switches, depending on the specific switch and application. The most common type is the single-pole, double-throw (SPDT) wiring diagram, which is used for switches that have two input terminals and one output terminal.

Other types of wiring diagrams include the double-pole, double-throw (DPDT) wiring diagram, which is used for switches that have four input terminals and two output terminals, and the triple-pole, double-throw (TPDT) wiring diagram, which is used for switches that have six input terminals and three output terminals.

SPDT Wiring Diagram

The SPDT wiring diagram is the most common type of wiring diagram used for pressure switches. It is used for switches that have two input terminals and one output terminal. The input terminals are typically labeled “COM” and “NO”, and the output terminal is labeled “NC”.

When the pressure switch is in the “off” position, the COM terminal is connected to the NO terminal. When the pressure switch is in the “on” position, the COM terminal is connected to the NC terminal.

DPDT Wiring Diagram

The DPDT wiring diagram is used for switches that have four input terminals and two output terminals. The input terminals are typically labeled “COM”, “NO”, “NC”, and “COM2”, and the output terminals are labeled “NO2” and “NC2”.

When the pressure switch is in the “off” position, the COM terminal is connected to the NO terminal and the COM2 terminal is connected to the NC2 terminal. When the pressure switch is in the “on” position, the COM terminal is connected to the NC terminal and the COM2 terminal is connected to the NO2 terminal.

TPDT Wiring Diagram

The TPDT wiring diagram is used for switches that have six input terminals and three output terminals. The input terminals are typically labeled “COM”, “NO”, “NC”, “COM2”, “NO2”, and “NC2”, and the output terminals are labeled “NO3”, “NC3”, and “COM3”.

When the pressure switch is in the “off” position, the COM terminal is connected to the NO terminal, the COM2 terminal is connected to the NC2 terminal, and the COM3 terminal is connected to the NC3 terminal. When the pressure switch is in the “on” position, the COM terminal is connected to the NC terminal, the COM2 terminal is connected to the NO2 terminal, and the COM3 terminal is connected to the NO3 terminal.

The main components of a wiring diagram for a pressure switch include:

Power Source

The power source provides electrical energy to the pressure switch system. It can be a battery, AC power supply, or other suitable source.

Pressure Switch

The pressure switch is the central component of the system. It monitors the pressure in a system and triggers an electrical signal when the pressure reaches a predetermined set point.

Load

The load is the device or circuit that is controlled by the pressure switch. It can be a pump, valve, or other electrical device.

Control Circuit

The control circuit provides the electrical pathway between the pressure switch and the load. It includes wires, terminals, and other components that connect the pressure switch to the load.

Types of Wiring Diagrams for Pressure Switches

wiring diagram for a pressure switch

Pressure switch wiring diagrams are essential for understanding the electrical connections and operation of pressure switches. Different types of pressure switches require specific wiring diagrams to ensure proper functionality and safety.

Single-Pole, Single-Throw (SPST)

SPST pressure switches have two terminals: a common terminal and a normally open (NO) terminal. When the pressure reaches the set point, the switch closes, connecting the common terminal to the NO terminal. This type of switch is commonly used in simple on/off applications.

Single-Pole, Double-Throw (SPDT)

SPDT pressure switches have three terminals: a common terminal, a normally open (NO) terminal, and a normally closed (NC) terminal. When the pressure reaches the set point, the switch switches from the NC terminal to the NO terminal. SPDT switches are used in applications where both on and off states are required.

Double-Pole, Single-Throw (DPST)

DPST pressure switches have four terminals: two common terminals, a normally open (NO) terminal, and a normally closed (NC) terminal. When the pressure reaches the set point, the switch closes both common terminals to the NO terminals. DPST switches are used in applications where multiple circuits need to be controlled simultaneously.

Double-Pole, Double-Throw (DPDT)

DPDT pressure switches have six terminals: two common terminals, two normally open (NO) terminals, and two normally closed (NC) terminals. When the pressure reaches the set point, the switch switches both common terminals to the NO terminals and the NC terminals to the NO terminals.

DPDT switches are used in applications where complex switching operations are required.

Tracing the Flow of Current

Once the power source has been identified, trace the flow of current through the circuit. This can be done by following the lines that connect the various components. The current will typically flow from the power source, through the pressure switch, and then to the load (e.g.,

a pump or solenoid valve).

Identifying the Control Circuit

The control circuit is responsible for controlling the operation of the pressure switch. This circuit typically includes a pressure sensor, which detects changes in pressure, and a control module, which interprets the sensor input and activates or deactivates the pressure switch.
