Frequently Asked Questions About Push Button Switches
What is a push button switch?
A push button switch is an electrical control device that changes a circuit state when pressed.It is widely used in industrial machinery,automation systems and control panels.
What is the difference between NO and NC push buttons?
NO (Normally Open) contacts remain open until the button is pressed, while NC (Normally Closed) contacts remain closed until activated.
What is the difference between momentary and latching push button switches?
A momentary push button only works while being pressed. After releasing the button, it returns to its original position.
A latching push button maintains its ON/OFF position after pressing until it is pressed again.
How do I choose the right push button switch?
Consider mounting size, voltage, current rating,contact configuration, IP protection level,material and application environment.
What sizes are available for push button switches?
Common installation dimensions include: 10mm, 12mm, 16mm, 19mm, 22mm, 25mm 28mm and 30mm.
What IP rating should I choose for outdoor applications?
IP65 is suitable for dust and water spray,while IP67 and IP68 are recommended for environments requiring higher waterproof protection.
How do I wire a push button switch?
The wiring depends on the contact type:
- NO contact: Connect to start/control circuits.
- NC contact: Used for stop or safety circuits.
- LED models: Require correct LED voltage connection.
Always check the product wiring diagram before installation.
Why does my push button switch stop working?
Common causes include incorrect wiring,contact damage, mechanical wear,overload and environmental factors.
Why does my push button switch get stuck?
Common reasons: Dust or dirt inside the switch、Incorrect installation、Mechanical wear、Damaged spring mechanism
Can a 12V push button switch be used on a 24V system?
For non-illuminated switches, it depends on the electrical rating.For illuminated switches, the LED voltage must match the power supply. A 12V LED may be damaged if connected to 24V.
Why does a push button switch burn out?
Common causes: Current exceeds rated capacity、Voltage overload、Frequent switching of high-power loads、Poor electrical connections
Can push button switches be customized?
Yes. Many manufacturers provide customization options: Logo printing、Custom shell colors、Wire length、Connector types.,etc
