If you are looking for a switch that can control the flow of electricity in a circuit, you might have come across two types of switches: dpdt momentary push button switches and conventional momentary push button switches. But what are the differences between them, and which one should you choose for your application? In this article, we will explain the features, advantages, and disadvantages of both types of push button switches, and help you make an informed decision.
What is a dpdt momentary push button switch?
A dpdt momentary push button switch is a switch that has two input terminals and four output terminals, and has six terminals in total. It can also be considered as two spdt switches combined. Dpdt stands for double pole double throw, which means that the switch can connect two pairs of terminals in two different ways. A momentary push button switch is a switch that works only when it is pressed, and returns to its original position when it is released. It is also known as a self-reset type or a non-latching type.
How does a dpdt momentary push button switch work?
A dpdt momentary push button switch works by temporarily connecting or disconnecting two pairs of terminals when it is pressed. For example, if the switch is in its default position, it can connect terminals A and C, and terminals B and D. When the switch is pressed, it can connect terminals A and D, and terminals B and C. When the switch is released, it goes back to its default position. This way, the switch can change the direction or polarity of the current in a circuit.
What are the advantages and disadvantages of a dpdt momentary push button switch?
A dpdt momentary push button switch has some advantages and disadvantages compared to a conventional momentary push button switch. Some of the advantages are:
- It can control two circuits or devices with one switch.
- It can reverse the direction or polarity of the current in a circuit.
- It can create complex switching patterns or logic functions.
Some of the disadvantages are:
- It has more terminals and wires, which can make it more complicated to install and use.
- It can cause short circuits or damage if it is not wired correctly or if it is used for incompatible loads.
- It can be more expensive and less available than a conventional momentary push button switch.
What is a conventional momentary push button switch?
A conventional momentary push button switch is a switch that has two terminals, and has two terminals in total. It can also be considered as a simple spst switch. Spst stands for single pole single throw, which means that the switch can connect or disconnect one pair of terminals. A momentary push button switch is a switch that works only when it is pressed, and returns to its original position when it is released. It is also known as a self-reset type or a non-latching type.
How does a conventional momentary push button switch work?
A conventional momentary push button switch works by temporarily closing or opening a circuit when it is pressed. For example, if the switch is in its default position, it can disconnect terminals A and B. When the switch is pressed, it can connect terminals A and B. When the switch is released, it goes back to its default position. This way, the switch can turn on or off a device or a circuit.
What are the advantages and disadvantages of a conventional momentary push button switch?
A conventional momentary push button switch has some advantages and disadvantages compared to a dpdt momentary push button switch. Some of the advantages are:
- It has fewer terminals and wires, which can make it easier to install and use.
- It has less risk of short circuits or damage if it is wired correctly and if it is used for compatible loads.
- It can be cheaper and more available than a dpdt momentary push button switch.
Some of the disadvantages are:
- It can only control one circuit or device with one switch.
- It cannot reverse the direction or polarity of the current in a circuit.
- It cannot create complex switching patterns or logic functions.
Which one should you choose?
The choice between a dpdt momentary push button switch and a conventional momentary push button switch depends on your application and your preferences. You should consider the following factors before making a decision:
- The number of circuits or devices that you want to control with one switch.
- The need to reverse the direction or polarity of the current in a circuit.
- The complexity of the switching patterns or logic functions that you want to create.
- The ease of installation and use of the switch.
- The risk of short circuits or damage to the switch or the circuit.
- The cost and availability of the switch.
In general, a dpdt momentary push button switch is more suitable for applications that require more functionality and flexibility, such as reversing motors, changing signals, or creating logic gates. A conventional momentary push button switch is more suitable for applications that require less functionality and simplicity, such as turning on lights, sounding alarms, or activating relays.
