Types of Push Button Switches
When it comes to wiring a push button switch, it’s important to understand the different types available. Depending on your specific needs, there are several options to choose from. Here are some common types of push button switches:
1. Momentary Push Button Switch:
A momentary push button switch is a type of switch that only makes contact while the button is being pressed. Once the button is released, the contact breaks and the circuit is interrupted. This type of switch is commonly used in applications where a temporary connection is needed, such as doorbells or garage door openers.
2. Toggle Push Button Switch:
A toggle push button switch is a type of switch that stays in the position it is pushed until it is pushed again. It has two stable states, on and off. When the button is pushed, the circuit is closed or opened depending on the initial state. This type of switch is commonly used in applications where a toggle function is required, such as power switches for lights or appliances.
3. Locking Push Button Switch:
A locking push button switch is a type of switch that locks in the position it is pushed and requires an additional action to release the lock. This type of switch is commonly used in applications where a secure connection is needed, such as alarm systems or emergency stop buttons.
4. Illuminated Push Button Switch:
An illuminated push button switch is a type of switch that has a built-in light source that illuminates the button when it is pressed. This type of switch is commonly used in applications where visibility is important, such as control panels or indicator lights.
- Momentary push button switch: Makes contact only while the button is being pressed.
- Toggle push button switch: Stays in the position it is pushed until it is pushed again.
- Locking push button switch: Locks in the position it is pushed and requires an additional action to release the lock.
- Illuminated push button switch: Has a built-in light source that illuminates the button when it is pressed.
Momentary Push Button Switch
A momentary push button switch, also known as a momentary switch or a momentary contact switch, is a type of switch that is designed to be pressed and released quickly, resulting in a momentary change in the state of the switch. This type of switch is commonly used in various applications where a temporary or intermittent control signal is needed. It is typically used to initiate an action or signal a specific event.
The momentary push button switch is composed of a button, a mechanical mechanism, and electrical contacts. When the button is pressed, it moves the mechanical mechanism, which allows the electrical contacts to come together or separate, depending on the design of the switch. This momentary contact creates a temporary electrical connection that triggers the desired action or event.
These switches are often used in electronic devices and control panels, where they are used for functions such as power on/off, reset, start/stop, or to activate specific modes or functions. They can also be found in various industrial and automotive applications, where they are used for tasks such as signaling, testing, or emergency stop.
When wiring a momentary push button switch, it is important to follow the manufacturer’s instructions and refer to the wiring diagram provided. Typically, these switches have two terminals or contacts, which should be connected to the appropriate power source or circuit. It is important to ensure that the switch is wired correctly to avoid any potential issues or malfunctions.
In conclusion, a momentary push button switch is a type of switch that is designed to provide a temporary electrical connection when pressed. It is commonly used in various applications where a momentary control signal is needed. When wiring this type of switch, it is crucial to follow the manufacturer’s instructions and refer to the wiring diagram to ensure proper installation and functionality.
Latching Push Button Switch
A latching push button switch is a type of switch that maintains its state once it is pressed. It features a mechanism that keeps the contacts closed or opened even after the button is released. This type of switch is commonly used in various electronic devices and applications.
One of the main advantages of a latching push button switch is that it eliminates the need for continuous pressure on the button to maintain the desired state. Once the button is pressed, the switch maintains that state until it is pressed again, either to toggle back to the original state or to switch to a different state. This makes it convenient for applications where a constant input is not required, such as on/off switches or mode selection switches.
The mechanism of a latching push button switch typically involves a latch or a toggle mechanism that holds the contacts in position. When the button is pressed, it engages the latch or toggle, locking the contacts in either the closed or open position. The latch or toggle mechanism ensures that the contacts remain in that position until the button is pressed again, causing the latch or toggle to release and allow the contacts to switch to the opposite position.

The normally open terminal is typically labeled as “NO” or “Normally Open,” while the normally closed terminal is labeled as “NC” or “Normally Closed.”
It is crucial to understand the function of each terminal to wire the switch correctly. The common terminal is where the incoming power is connected. The normally open terminal is effectively an open circuit, but it becomes connected to the common terminal when the switch is pressed. On the other hand, the normally closed terminal is connected to the common terminal when the switch is not pressed and disconnects when the switch is pressed.
- Common Terminal (C): Connect the incoming power wire to this terminal.
- Normally Open Terminal (NO): Connect the desired output wire to this terminal.
- Normally Closed Terminal (NC): Connect the desired output wire to this terminal.
By correctly identifying and connecting the wires to the appropriate terminals on the push button switch, you can ensure that the switch operates as intended and effectively controls the desired circuit or device.
Connect the wires to the terminals
When wiring a push button switch, it is important to connect the wires to the correct terminals to ensure proper functionality. The terminals on a push button switch are typically labeled with “NO” (normally open) and “COM” (common).
To connect the wires, first identify which wire is the positive wire and which is the negative wire. The positive wire is typically red or marked with a plus sign (+), while the negative wire is usually black or marked with a minus sign (-).
- Connect the positive wire to the “NO” terminal of the push button switch. This is the terminal that is not connected to the common wire when the switch is in its resting state.
- Connect the negative wire to the “COM” terminal of the push button switch. This is the terminal that is connected to the common wire when the switch is in its resting state.
Make sure to tighten the terminal screws securely to ensure a good connection. Once the wires are connected, test the push button switch to make sure it is functioning properly. Pressing the button should close the circuit, allowing for the flow of electricity.
