In recent times, the overall electrical industry has maintained a steady development momentum. As a core component in electrical connections, terminal blocks have benefited from the sustained growth of sectors such as industrial automation, new energy (photovoltaic/storage/charging piles), smart grids, rail transit, and data center construction. The market scale has steadily expanded, and technological iteration has accelerated. Among these trends, the popularization of Push-in (tool-free) terminals has emerged as one of the most prominent industry developments. Meanwhile, the technological strength of domestic enterprises has continued to advance, with a gradual breakthrough in the high-end market.
I. Industry Market Scale and Overall Growth Trend
In 2026, the global terminal block market is expected to reach 8.93 billion USD, with a compound annual growth rate (CAGR) of 6.2%. The Asia-Pacific region accounts for as much as 42.7% of the total market share. As the core growth engine of the Asia-Pacific region, China has continuously promoted industry expansion driven by the strong demand from downstream industries. In terms of product structure, DIN rail terminals still dominate the market.

Among the segmented categories, Push-in (tool-free) terminals, PCB mount terminals, and fuse/distributed terminals are the three fastest-growing categories. Among them, Push-in terminals lead with a CAGR of 7.08%, becoming the core driver of industry growth. Their popularization speed and application scope continue to improve, making them the preferred wiring solution for various downstream fields.
II. Popularization Status of Push-in (Tool-free) Terminals: Data-driven, Comprehensive Penetration
In recent years, Push-in terminals have gradually replaced traditional screw terminals by virtue of their core advantages of “efficiency, convenience, and reliability”. The speed of their popularization has accelerated continuously. Relevant data clearly shows their industry penetration trend, making them the core development direction of the terminal block industry:
-
Market Scale Level: The global Push-in terminal market reached 2.401 billion USD in 2025 and is expected to increase to 2.509 billion USD in 2026. It is estimated that by 2035, the market size will exceed 3.729 billion USD, with a CAGR of 4.5% during 2026-2035. The growth momentum is stable, making it one of the fastest-growing segmented categories in the terminal block industry.
-
Penetration Rate Level: In China’s industrial control field, the penetration rate of Push-in terminals has rapidly increased from 21% in 2018 to 47% in 2023, more than doubling in just 5 years. In 2025, the market share of spring-loaded terminals (including Push-in technology) in the rail-mounted terminal market rose to 38.7%, while the share of traditional screw terminals is declining year by year. In 2023, its share dropped from a dominant position to 52.3%. The substitution effect of Push-in terminals is increasingly prominent.
-
Application Scene Penetration: From the perspective of application fields, the industrial field is the core demand market for Push-in terminals, accounting for more than 32% of industrial applications in 2023. In the new energy field, especially in photovoltaic, energy storage, and charging piles, Push-in terminals are preferred for rapid deployment and high-reliability needs, with continuously improving penetration rates. The penetration rate in 800V vehicle high-voltage distribution boxes has reached 78%. In commercial buildings, lighting control, HVAC, and fire safety panels, Push-in terminals have also become the standard configuration. In more than 68% of small and medium-sized electrical projects in North America, Push-in terminals have been used for circuit wiring.
-
Efficiency and Reliability Data: Compared with traditional screw terminals, Push-in terminals do not require tools such as screwdrivers. Wires can be automatically locked by inserting, which improves the installation speed by more than 3 times. A single person can complete the wiring of a single point within 10 seconds, saving 75%-80% of working hours compared with traditional screw terminals. According to the application of a panel manufacturer, the assembly time of a single control cabinet is shortened by 2 hours, greatly improving production efficiency. At the same time, its spring clamp structure can provide continuous and stable contact pressure, with better vibration resistance than screw terminals. It can effectively avoid wiring loosening in vibration environments and reduce wiring errors caused by human factors. According to relevant surveys, after using Push-in terminals, the wiring error rate can be reduced by more than 60%, and maintenance efficiency is improved by 50%.
-
Product Performance Upgrade: Current mainstream Push-in terminals have achieved comprehensive performance upgrades. Commercial-grade products can support a maximum voltage of 600V and a current of 30A, with a wiring range covering 0.08mm²-25mm², suitable for single-strand hard wires, multi-strand soft wires and other types of wires. In terms of materials, high-conductivity copper alloy and halogen-free PA66 flame-retardant materials are used, which are high-temperature resistant and corrosion-resistant, adapting to the wide temperature range of -40℃~+100℃, and the highest protection grade can reach IP68, which is suitable for various complex environments such as outdoor and industrial harsh environments, further promoting the expansion of its popularization scope.
III. Industry Technology Trends and Policy Orientation
In Q1 2026, the technological development of the terminal block industry focuses on the four major directions of “efficiency, intelligence, greenness, and reliability”. In addition to the popularization of Push-in technology, the industry also shows three major trends: first, high-density and multi-layer design has become the mainstream. Double-layer, three-layer terminals and multi-wire terminals are gradually promoted, which effectively improves the space utilization rate in cabinets; second, the intelligent upgrade is accelerating. Terminals are integrated with temperature and current sensors, supporting IO-Link/Modbus protocols to realize status monitoring, early warning and predictive maintenance, which is in line with the national standard “General Requirements for Status Perception of Intelligent Manufacturing Equipment” implemented in 2026; third, green compliance has become a rigid requirement. RoHS, halogen-free, low VOC, and recyclable design have become industry standards, complying with global environmental protection new regulations.
At the policy level, the “General Requirements for Status Perception of Intelligent Manufacturing Equipment” were officially released in 2026, promoting perception, edge diagnosis, and safety isolation to become the standard configuration of high-end terminals. At the same time, the “Industrial Internet Identification Analysis – Coding Standards for Connecting Devices” continues to be implemented.
