Pushbutton switches are integral components in numerous electrical applications. While they are reliable and easy to use, these switches can encounter issues over time.
Let’s talk about the common problems plaguing pushbutton switches, including wall pushbutton switches, and offer effective solutions to get them back in working order.
4 Common Problems of Push Button Switches
Pushbutton switches have 4 common problems: jamming, intermittent response, arcing, and physical damage.
Here’s a more detailed explanation for each and how you can repair them.
- Sticking or Jamming Buttons
Sticking or jamming buttons are often caused by dirt, debris, or corrosion that accumulate within the switch mechanism, hindering the smooth movement of the button.
The solution? Cleaning and lubricating. Carefully disassemble the switch and clean the internal components with a contact cleaner or isopropyl alcohol. You can also apply a small amount of dielectric grease to the moving parts to ensure smooth operation.
- Intermittent or No Response
Intermittent or worse, lack of response is caused by loose or worn-out contacts, damaged wiring, or faulty internal components that can disrupt the electrical connection.
The solution is to tighten any loose screws or terminals. Also, inspect the contacts for signs of wear, corrosion, or damage. Clean or replace them if necessary. If the internal mechanism is faulty, consider replacing the entire switch.
Electrical Arcing or Sparking
Electrical arcing or sparking is caused by high voltage or current surges that can cause arcing or sparking between the contacts, leading to damage and potential hazards.
To fix, install surge protectors or voltage regulators to safeguard the switch from electrical fluctuations. Ensure the switch is rated for the voltage and current of the circuit it’s connected to.
Physical Damage
Physical damage is caused by accidental drops, impacts, or excessive force that can crack the housing, break internal components, or dislodge wires.
The solution is to assess the extent of the damage. Minor cracks can be repaired with epoxy, but significant damage may necessitate switch replacement.
Prevention and Maintenance: 3 Tips
- Regular Cleaning
Periodically clean the switch’s exterior and, if possible, the internal contacts.
- Proper Installation
Ensure the switch is correctly installed and wired according to manufacturer instructions.
- Environmental Protection
Shield the switch from excessive moisture, dust, and extreme temperatures.
