When buying push button switches, most engineers start with the basic specifications: panel cutout, contact configuration, electrical rating, protection level and operating life.
For some projects, certification is also part of the specification.
TUV certification is one of the requirements that buyers may look for when sourcing push button switches for industrial equipment and control panels.
ONPOW manufactures TUV certified push button switches for a range of industrial applications.
TUV Certification and Push Button Switches
A push button switch is a small component, but it can have an important role in a machine.
Operators use push buttons to start and stop equipment, reset a system, select a function or control a process. If the switch is installed on equipment that will be sold in different markets, buyers may also need specific product certifications.
This is where TUV certification can become a consideration during component selection.
For machine builders and control panel manufacturers, having the required certification can also make the purchasing and approval process easier.
What Should You Check Before Ordering?
TUV certification alone does not tell you whether a push button is suitable for your application.
There are several other specifications to check.
Panel cutout
The mounting hole needs to match the push button. Common sizes include 16mm, 19mm, 22mm and 30mm.
Contact configuration
Depending on the circuit, you may need NO, NC, or both NO and NC contacts.
Electrical rating
Check the voltage and current requirements of the circuit before selecting the switch. The rating of the push button should be suitable for the actual application.
IP protection
If the switch is used in an environment with dust, water or oil, protection is worth checking carefully. Depending on the application, buyers may look for IP65, IP67 or higher.
Material
Metal push buttons are commonly used on industrial control panels and machinery where a stronger front panel component is required. Plastic push buttons can be a practical choice for applications where cost and weight are more important.
Switching life
For equipment that is operated hundreds or thousands of times a day, mechanical and electrical life should also be considered.
Where Are TUV Certified Push Buttons Used?
There is no single application for a TUV certified push button.
They can be found in industrial control panels, automation equipment, machine tools, packaging machines, transportation equipment and other electrical control systems.
The required specification will be different from one machine to another.
For example, one customer may need a standard momentary push button for a control cabinet. Another may require a metal illuminated push button with NO/NC contacts and a higher IP rating.
The certification may be the same, but the actual switch specification can be quite different.
Choosing a Push Button Manufacturer
For OEM customers, buying a push button is usually not just about finding the lowest unit price.
Product consistency, available specifications, technical drawings, customization and production capability can all affect the final decision.
Working directly with a manufacturer can also make communication easier when a project requires a particular panel size, contact arrangement, LED voltage, button style or housing material.
ONPOW has been manufacturing push button switches for industrial applications for many years. Its product range includes metal push buttons, illuminated push buttons, emergency stop switches, selector switches and other control switches.
For customers who require TUV certified push buttons, ONPOW can provide the corresponding product information and specifications for project evaluation.
Need a TUV Certified Push Button Switch?
Before sending an inquiry, it is helpful to have the basic requirements ready:
Panel cutout size
Contact type
Voltage and current
IP rating
