240V push button switch

Normally closed momentary switch is a type of electronic switch that is typically used in electronic circuits or control systems.

Normally closed momentary switches are closed when not pressed, open briefly when pressed, and return to a closed state immediately upon release.

The basic principle of this type of switch is to use a spring or other mechanical structure that keeps the switch closed when no external force is applied.

When the switch is pressed by an external force, the mechanical structure releases and opens the switch, but as soon as the external force stops acting, the mechanical structure immediately returns to its original state, causing the switch to close again.

Normally closed momentary switch VS momentary pushbutton switch

This type of switch is commonly used in applications where a brief circuit connection or disconnection is required.

For example, when the power button on a computer case is pressed, it triggers a normally closed momentary switch that causes the power circuit to open, allowing the computer to boot up.

When the button is released, the switch immediately reverts to the closed state to keep the power circuit connected.

In summary, a normally closed momentary switch is a switch that closes when not pressed, opens temporarily when pressed, and closes again immediately upon release.

Here’s a table outlining the similarities and differences between a Normally Closed Momentary Switch and a Momentary Push Button Switch:

Normally Closed Momentary Switch Momentary Push Button Switch
Normally closed state Yes No
Normally open state No Yes
Operation Press to momentarily open Press to momentarily close
Contact configuration Normally closed (NC) Normally open (NO)
Reset mechanism Spring or mechanical structure Spring or mechanical structure
Typical use Interrupting current flow Completing current flow
Application examples Emergency stop buttons, Doorbells, keyboards,
safety switches game controllers

These are the main similarities and differences between a Normally Closed Momentary Switch and a Momentary Push Button Switch.

Wiring Guide for 5-Pin Normally Closed Momentary Switch with Indicator Light

When it comes to connecting a 5-pin Normally Closed Momentary Switch with an indicator light, the following wiring configuration can be followed:

  1. Identify the pins: The switch will have five pins labeled as C, NC, NO, and two lamp pins (L1 and L2).
  2. Common connection: Connect the common pin (C) to the common contact or power source in your circuit.
  3. Normally Closed connection: Connect the normally closed pin (NC) to the desired component or circuit that you want to interrupt or deactivate when the switch is pressed.
  4. Normally Open connection: Connect the normally open pin (NO) to the desired component or circuit that you want to activate or complete when the switch is pressed.
  5. Indicator light connection: The two lamp pins (L1 and L2) are used to connect the indicator light. These pins are typically located on either side of the NO pin. Connect one terminal of the indicator light to one of the lamp pins (L1 or L2), and the other terminal to the positive terminal of your power supply. It’s important to ensure the indicator light’s voltage matches your power supply voltage.
  6. Polarization: For the indicator light, there is no specific positive or negative polarity. It can be connected in either orientation.

Note: It is critical to verify the specific pinout and configuration of your 5-pin normally closed momentary switch, as this may vary between manufacturers or models. filn recommends that you always consult the manufacturer’s data sheet or wiring diagram for accurate and detailed instructions.

When working with electrical connections, please remember to take appropriate safety precautions and ensure that switches and indicators are compatible with the voltage and current requirements of your circuit.
