Industrial automation has changed a lot over the past few years.
Machines are running faster. Production lines are more connected. AGVs move materials around factories, robots handle more processes, and CNC machines can run for long periods with less operator involvement.
But even with all this automation, there is still a place for a simple push button.
Start. Stop. Reset. Manual operation. Emergency stop.
The functions are simple, but the requirements for the switch are not.
For a push button manufacturer, the changes happening in industrial equipment can be seen quite clearly in the requirements customers bring to us.
Buttons Are Being Used More Frequently
A button on a traditional machine may only be operated occasionally.
On an automated production line, the same button can be pressed many times every day. Some equipment runs continuously across multiple shifts, so mechanical and electrical reliability become more important.
Customers are paying closer attention to operating life, contact performance and consistency between batches.
This is also where a low-cost switch can become an expensive choice. If a button fails after the machine has been installed, the cost may include maintenance, downtime and service work, not just the price of the replacement switch.
AGVs and Mobile Equipment Bring New Requirements
AGVs are a good example.
A switch installed on an AGV may be exposed to vibration, dust, changes in temperature and occasional moisture. The requirements are different from a button installed inside a clean control cabinet.
Depending on the equipment, customers may need higher IP protection, stronger construction or specific materials.
IP65, IP67 and IP68 are common requirements in applications where protection against dust and water is important.
But an IP rating should not be considered by itself. The installation position, operating environment and expected usage also need to be taken into account.
ONPOW has developed waterproof and anti-vandal push buttons for applications where environmental protection is important.
Robots Still Need Physical Controls
Robots can perform many operations automatically, but operators still need to interact with the equipment.
During setup, maintenance or troubleshooting, an operator may need to start a machine, stop a process, reset an alarm or change the operating mode.
This is why physical controls remain common on robot systems and control panels.
Illuminated push buttons can show operating status. Selector switches can be used for different operating modes. Key lock switches can restrict operation where necessary.
A touchscreen can display a lot of information, but a physical button has one obvious advantage: the operator can find and operate it immediately.
Emergency Stop Is Not Going Away
More automation does not mean less need for emergency stop controls.
In fact, automated equipment often has more moving parts and more complex operating processes. A clearly identifiable emergency stop remains an important part of many machines.
The details matter.
The button size, contact configuration, reset method, mounting dimensions and protection level all need to match the equipment.
ONPOW produces emergency stop switches in different designs and configurations for industrial applications.
For machine builders, the important thing is not simply having a red mushroom button on the panel. The emergency stop needs to work as part of the overall control and safety system.
Control Panels Are Becoming More Application-Specific
There was a time when many machines could use the same standard button.
Today, equipment is more specialized.
A customer may need a particular mounting size, a certain button color, a specific LED, a different terminal or a special contact arrangement.
Sometimes a standard product is enough. Sometimes it is not.
This is where OEM capability becomes useful.
ONPOW works with customers on product dimensions, materials, illumination, terminals, contact configurations and other requirements. Customers can also provide drawings or samples when a project requires a modified or new structure.
For equipment manufacturers, having this kind of support can make the development process much easier.
Physical Buttons and Digital Controls Will Continue to Work Together
Industrial automation is often associated with touchscreens, PLCs, sensors and software.
That does not mean physical switches are disappearing.
In many machines, the two work together.
The touchscreen can provide information and more complicated settings. A physical button can provide a direct action for functions that need to be quick and obvious.
Emergency stop is the clearest example, but start, stop, reset and manual controls are also commonly handled with physical switches.
The trend is therefore not simply from buttons to touchscreens.
In many applications, it is about finding the right combination of physical and digital controls.
Consistency Becomes More Important in Mass Production
Automation also changes the expectations placed on the component supplier.
When a machine manufacturer produces a few prototype machines, a small variation may not cause a major problem.
When the same machine goes into mass production, it is a different situation.
The approved sample needs to be followed by hundreds or thousands of products with the same specifications and performance.
This requires stable materials, controlled production processes, reliable tooling and proper inspection.
It is one of the areas where manufacturing experience becomes important.
What We Are Seeing at ONPOW
ONPOW has been making push button switches since 1988.
Over the years, the product range has grown to around 40 series, supported by more than 1,500 sets of molds and over 70 patents.
The range now includes metal and plastic push buttons, illuminated switches, emergency stop switches, selector switches, key lock switches, piezo switches, touch switches, indicator lights and other control components.
We also see that customers are becoming more specific about what they need.
They are not simply asking for a "push button."
They may come with a drawing, a sample or a machine design and ask about mounting dimensions, materials, IP protection, illumination, contact configuration, certification or long-term supply.
That changes the role of the supplier.
The job is not only to manufacture the switch. It is also to understand where the switch will be used and whether the product is suitable for the machine.
The Push Button May Be Small, but the Requirements Are Not
Industrial equipment will continue to become more automated.
AGVs will become more common. Robots will take on more tasks. Production lines will become more connected, and operators will have more information available through digital systems.
But machines will still need simple, reliable physical controls.
A button may only take a few centimeters of space on a control panel.
Behind that small component, however, are questions about mechanical life, electrical performance, materials, protection, testing, manufacturing consistency and application requirements.
That is where the difference between a standard component supplier and an experienced push button manufacturer becomes clear.
At ONPOW, this is the work we have been doing since 1988.
The machines are becoming smarter. The button still needs to work when someone presses it.
