A pushbutton may be small, but it can play a critical role in determining whether an entire machine starts, stops, and operates as intended.

In sectors such as renewable energy, industrial automation, and EV charging infrastructure, electrical control cabinets are responsible for essential functions including equipment start/stop operations, status indication, and function switching. Pushbuttons and switches serve as the most direct interface between operators and equipment. Their operating feel, control reliability, and long-term stability all contribute to the overall performance of the system.

Recognizing the growing demand for reliability, application flexibility, and supply continuity, Acxion develops and manufactures pushbuttons and switches for industrial control applications. With a focus on both imported-brand alternatives and high-quality domestic products, Acxion has established a product portfolio covering plastic pushbuttons, metal pushbuttons, and illuminated pushbutton indicators. The company also provides customized solutions for specialized operating environments, giving customers greater flexibility in selecting control components.

1. Four Core Product Series for Mainstream Industrial Control Applications

Acxion pushbuttons and switches cover commonly used panel cutout sizes of 16 mm, 22 mm, and 30 mm, with panel-mounted and PCB-mounted installation options to accommodate different electrical control cabinets and industrial equipment structures.

From standard control applications to specialized environments requiring higher levels of protection, durability, and environmental resistance, Acxion offers product combinations based on different materials, structures, and functions.

For customers seeking alternatives to imported brands, Acxion's product capabilities provide a practical starting point:

• HB2 and XH2 Series: Designed as pin-to-pin alternatives to Schneider Electric's classic XB2 series, with 1:1 compatibility in dimensions and mounting interfaces.

• LA135 Series: A cost-effective plastic pushbutton series widely used in electrical distribution cabinets, power control cabinets, and EV charging equipment.

• HBM Series: Extends the product portfolio into metal pushbutton indicators, combining control and status indication in a single component.

The relevant products have obtained certifications including CCC, CE, and RoHS. Protection levels and other specifications can also be customized according to application requirements.

Product selection does not have to be complicated. The five key factors to consider are panel cutout size, rated electrical parameters, service life, protection rating, and operating temperature.

2. Beyond Standard Products: Meeting the Demands of Specialized Applications

Standardized products can meet the requirements of conventional equipment. However, specialized operating environments often introduce challenges that go beyond standard specifications, including higher protection ratings, complex mounting structures, demanding temperature and humidity conditions, ultraviolet exposure, salt spray corrosion, and special gas environments.

Acxion's customization capabilities are designed to address these requirements.

With in-house R&D and manufacturing capabilities, Acxion can develop products based on customers' actual equipment structures and operating conditions. Customization may cover product dimensions, external structures, protection solutions, materials, contacts, and performance specifications, extending product selection from standardized configurations to application-specific solutions.

The following three completed projects demonstrate how Acxion applies this capability in practice.

• Case Study 1 | Integrated Emergency-Stop Button Box with Protective Cover

A customer required a customized emergency-stop button box with a P22 panel cutout and an integrated protective cover, with a target protection rating of IP65.

Rather than adopting the conventional approach of combining a pushbutton with a separate protective cover, Acxion developed an integrated design that combined the emergency-stop button and protective cover into a single structure.

This structural optimization achieved the required IP65 protection rating while creating a cleaner overall appearance. It also eliminated the need for separate protective-cover installation, making on-site assembly more convenient.

• Case Study 2 | UV-Resistant Emergency-Stop Button for an Energy Storage Project

Compared with conventional industrial environments, certain energy storage applications require equipment to withstand more demanding outdoor and complex operating conditions.

An energy storage customer specified a series of requirements for an emergency-stop button, including:

• Altitude above 5,000 meters.

• High-temperature and high-humidity conditions of 85°C/85% RH.

• Low-temperature operation at -40°C.

• UV resistance without discoloration.

• Resistance to corrosion from special gases.

• 500-hour cyclic salt spray testing.

• IP66 protection rating.

These requirements meant that the product needed to maintain not only basic functionality, but also stable mechanical, electrical, and appearance performance under extreme environmental conditions.

To meet the project requirements, Acxion developed a customized solution covering materials, structure, contacts, and protection performance.

High-performance plastic compounds and metal components were selected to improve resistance to high temperatures, humidity, UV exposure, and corrosive environments. The contacts received special gold plating treatment to reduce the risk of contact oxidation, abnormal contact performance, and functional failure.

The product also underwent internal and third-party certification testing, with verification covering high and low temperatures, humidity, UV exposure, special gases, cyclic salt spray, and protection performance.

The final product met the project's specified environmental requirements, providing a more reliable control solution for safe operation of energy storage equipment in complex environments.

• Case Study 3 | Customized Pushbuttons for CNC Machine Tools

Inside machine tools, pushbuttons may be directly exposed to cutting fluids and machining debris. They may also be cleaned regularly using compressed air.

A customer required a product with a service life of at least one year, resistance to oil and corrosion, a fully enclosed structure, and a sealing gasket at the mounting surface to prevent oil and contaminants from entering.

Acxion developed a customized solution combining an IP67 metal pushbutton with a nitrile rubber protective cover, integrated into a high-performance plastic housing.

The resulting design provides a more enclosed structure for maintaining stable and reliable operation in environments exposed to oil contamination and machining debris.

3. From a Single Pushbutton to a Complete Control Component Solution

From plastic pushbuttons to metal pushbuttons, illuminated indicators, and application-specific customized products, Acxion is building more than a product portfolio. It is developing a broader capability to support industrial control applications across different operating environments.

In sectors including energy storage, EV charging, logistics elevators, and industrial automation, customers can select products based on standard specifications or work with Acxion to develop customized solutions for specific dimensions, structures, protection requirements, and environmental conditions.

Standard products address conventional applications. Customization extends product capabilities to specialized operating environments.

Acxion will continue to build on its in-house R&D and manufacturing capabilities to provide more reliable, flexible, and application-oriented pushbutton and switch solutions for industrial control applications.
