What is a 19MM Momentary Switch?

A momentary switch is an electrical switch that remains active or “on” only when pressed and returns to its default position (typically “off”) upon release. Essentially, it’s a temporary switch that won’t maintain its state without continuous pressure.

Momentary Switch Common Applications:

Doorbell Buttons: Activate only when pressed.

Automotive Momentary Switch: Used in cars or yacht switches.

Industrial Machinery: For safety reasons, some machines require an operator to continuously press a button to operate.

Key Features of a Momentary Switch:

1.Temporary Activation: The switch activates only during the press.

2.Automatic Reset: It auto-returns to its default position when the pressure is removed.

3.Versatility: Used in various applications, from doorbell buttons to computer keyboards.

How Does a Momentary Switch Work?

When you press a momentary switch, it completes an electrical circuit. As soon as you release it, the circuit disconnects, and the switch goes back to its original position.

Types of Momentary Switches:

Normally Open (NO): The circuit is typically off and only closes when the switch is pressed.

Normally Closed (NC): The circuit is typically on and disconnects when the switch is pressed.


Safety: Prevents accidental continuous operation, especially in industrial settings.

Control: Allows precise control over device functions.

Durability: Due to their return to a neutral position, there’s less wear and tear on the switch mechanism.


Momentary switches are indispensable components in many devices and machinery. Their design ensures safety, precision, and durability, making them invaluable in numerous applications. Whether pressing a computer key or using industrial equipment, momentary switches play a crucial role in ensuring efficient and safe operation.

How to Wire A Momentary Switch ?

first of all we need to know that the 12V Momentary Switch product has 4 pins. In which the red line (C) closest to the power supply and the black line (NO) far from the power supply are the switch pins, the other two red lines and black lines are light pins, the light pins are regardless of positive pole or negative pole.

There are two types of wiring, see the picture below.

What’s the first way for the button connection ?

1.The positive pole of the power supply is connected to the switch C pin red wire and the LED lamp pin red wire (+) , and the other NO pin black wire is connected to the positive pole of the bulb device.

2.Connect the negative pole of the power supply to the negative pole of the bulb deviceand the LED lamp pin black wire(-).

 Switch function:

The  Switch is locked and the bulb device starts.

The  Switch is reset, the bulb device is turned off and the light is always on.
