Have you ever pressed a button and been met with silence? Or did it glow only to dim shortly after? No doubt illuminated push button switches may look simple, but a small problem in them can cause big problems. Understanding how these switches function and how to troubleshoot them is vital for anyone looking to save time and avoid stress. Here, we show the most frequent issues and offer handy tips to troubleshoot so the switches keep functioning as intended. So, let’s get started!
1) What is an illuminated push button switch?
An illuminated push button switch is a type of control switch that functions by turning on once pressed or powered. Its prime use is to control on or off equipment like machines as well as provide a visual signal that confirms the switch action.
Primarily, the light containing the switch is fitted with peripherals making it easier for people in low light surroundings. To be straightforward, in many systems, the light will only be active when the push switch is turned on. For instance, the light will glow when the button on a machine is pressed, indicating that it’s running.
What is Illuminated push button switch
Like any other switch, illuminated push button switches come in many forms including the color, shape, and size. Some are round and some are square. The round ones are usually more compact than the square button switches. Moreover, some types light up when pressed, while other types stay lit as long as current flows through the switch.
Apart from this, the color of the light also varies, red, green, or blue depending on what function it shows. Stops are customarily represented in red and the activity or on functions is indicated in green. Well, these switches are built to be strong and reliable. Many incorporate waterproof or dustproof features. This makes it ideal for use in tough locations like factories, vehicles or outside.
2) Illuminated Push Button Switch Working Principle
The illuminating switch consists of two different components, which is the electrical switch and light source. Both components work synergistically to achieve a common goal which is the control of a circuit and show a sign visually at the same time.
While performing an action, you press the button, it turns on the switch which breaks or makes an electrical junction. This will allow or stop the flow of current to a certain device. There are contact points within the switch, or in this case, inside the switch there are contact points. With every action taken that is where the button is pressed there is a possibility that the contacts either touch or separate, that comes down to the type of switch you use.
At the same time, the light source inside the switch turns on or changes as per the circuit. Typically, the light is emitted by an LED. LEDs are small and bright and do not consume a lot of power. Some switches have the LED connected to the primary circuit; others have a secondary line dedicated to lighting.
Illuminated push button switch working principle
In many systems, the light will only be on if the switch is pressed. In other configurations, the light remains illuminated, allowing the button to be easily located, whether it is pressed or not.
Moreover, some switches are provided with a small resistor with a LED which other users as switch devices use to adjust the power to the LED. This ensures that the light does not get damaged due to excessive voltage. Apart from this, it is easier to install because all the components are integrated into one body.
3) Common Issues and Their Causes
Although an illuminated switch push button is designed for a long lifecycle, it might experience some of the common issues listed below:
i) Switch Not Responding
If the switch is pressed but does nothing, it likely stems from a problem with the internal contacts. A connection can also be hindered by dust, dirt, or moisture. Failure of contacts or broken internal springs can also prevent the switch from functioning. Another cause can be loose or broken wires at the connection points which can lead to disconnection.
ii) LED/ Illumination Not Working
When the button is operational but the light remains off, there is a strong case for the LED being burnt. This situation can arise when there is a suffocating current flow through the light and no resistor is present. One other reason relates to wiring; a broken wire or botched soldering inside the switch can also be the reason. Sometimes, it is simply the power supply of the LED which is at fault.
iii) Switch sticking and failing to return
If a button is hard to press, or stays pressed in, something may be lodged within. This is typical in dusty or greasy settings. Furthermore, if the spring within the switch is broken or too old, the button will not return to its original location after it has been pressed.
iv) Unexpected or Intermittent Operation
Intermittently, the switch may function on a random basis, and so may the light. A damaged wire or inadequate contact within the switch may be responsible for this. Sometimes, machine vibrations can shake wires loose, leading to erratic behavior.
v) Feels Hot When Operating
Feeling hot to the touch can be a potential problem. The switch is likely to become too hot if there is too much current passing through. This would indicate that excess current is being directed at the switch which is not a good sign. Alternatively, poor cabling and short circuiting can increase temperature greatly.
4) Preventive Maintenance Tips
Regular maintenance of the illuminated push button switches extends their life and enhances performance. These are some common issues that could be avoided if simplistic actions are taken routinely.
Preventive maintenance tips for Illuminated push button switch
! Clean the Switch Surface: Dust, grease, and moisture could accumulate over time. To clean the face of the switch, utilize a dry and soft cloth. For stubborn spots, use a cloth damped with alcohol. Never spray liquid directly onto the switch.
! Check for Loose Connections: Loose connections could lead to malfunctioning or complete failure of the switch. Now and then, inspect the wiring from behind the panel. Observe all terminals and ensure they are tight and the wires are secured.
! Test the Light and Action: To check the button, press it and observe its smoothness as well as its quick return. Check the light, if it’s on the dim side or flickering, there might be a problem. Observing these early indicators can assist in addressing smaller issues prior to their escalation.
! Avoid Overloading: Ensure that the switch is operated within the corresponding current and voltage parameters. The switch or LED may be prone to damage if overloaded. Always consult the product label or manual for safe operating limits.
! Protect from Harsh Conditions: For use in dusty, wet, and highly vibrating areas, use a switch that has the needed protection features such as anti-vibration or waterproof capabilities. If the switch is not sealed, place it in a protective box to avoid external components.
! Replace Broken Components Promptly: If a button doesn’t work or starts to stick, replace the damaged parts quickly. You know if replacement is delayed it may lead to bigger problems.
! Conduct Routine Maintenance: Carrying out an inspection every few months will make it easier for any early signs of wear to be spotted. Look at the button, is it loose? The light, is it bright? Damage of any kind should be checked for. Early actions allow for prevention of major failures.
