The global relay market size was valued at USD 9.33 Billion in 2025. The industry is expected to grow at a CAGR of 6.00% during the forecast period of 2026-2035 to reach a value of USD 16.71 Billion by 2035. The market growth is gaining momentum as the twin forces of clean energy deployment and electrified mobility demand more robust, compact, and high-voltage switching components.
With the transformation of energy infrastructure to battery-based storage, EV charging stations, and solar-powered inverters, component makers are observing rising demand in the relay market, especially for relays that meet very strict safety, reliability, and size standards. To cite an instance, OMRON introduced its new G9EK high voltage DC relay in April 2025, which is a small, gas less relay that can cut off 500 VDC at 120 A and is aimed at energy storage of the next generation, EV charging systems, and DC equipment. On the other hand, Panasonic Industry debuted the HE A power relay in July 2024 which is a multi-purpose power relay designed for solar inverters and high load energy management. The HE A series is capable of a carrying capacity of up to 110 A and can switch high current in a very small form factor, thus it can be used in PV systems, inverters, and energy storage solutions.
These moves signify how relay producers are not only reacting to the demands of the energy transition but also are going ahead to enable it. By providing high voltage, high-current, compact, and long-lasting relay solutions that are specifically designed for EV, battery storage, and renewable energy systems, they make it easier for OEMs to simplify powertrain and inverter designs, which is supporting the global relay market expansion.

With the high demand for such features as a high switching frequency, durability, and minimal maintenance, industrial and commercial machinery are looking for solid-state relays (SSRs) to fulfil those needs. To meet such demands in a variety of markets Littelfuse, Inc. came up with the SRP1 SSR family in August 2024. The devices of this SSR family are characterized by the prolonged service life, improved resistance to mechanical wear, and reliable operation under harsh conditions. More and more low downtime and longer maintenance intervals industrial sectors will be so protected by these SSR product innovations that they will move away from traditional electromechanical relay usage thus the SSR segment will grow in the relay market.
The mergers or acquisitions activities of relay and switch gear companies significantly influence those companies' technological capabilities and geographical coverage. As an instance, in November 2023 Standex International Corporation made public the decision to go for an agreement with Sanyu Switch Co., Ltd. to take over the company, a Japanese reed relay and switch manufacturer. With that acquisition, Standex not only expanded its line of relays and switches but also increased its global footprint. The consolidation fosters cross-selling, unified supply, and research and development (R&D) synergies, which in turn help the company to serve various end markets with more capacity and to reinforce its competitive positions.
The use of industrial automation on a large scale is one of the factors that contribute to the fast-growing demand in the smart relay market that support fault protection and real-time monitoring in an unstable power grid. Manufacturers and utilities are emphasising on systems that can detect anomalies at an early stage and thus avoiding expensive outages or equipment failures. Siemens introduced its SIRIUS 3UG5 monitoring relay series in August 2023 to address the need for faster response to incidents and asset protection by detecting phase loss, voltage and frequency variations, and other disturbances. As automation penetrates more and more factories, infrastructures, and utilities, the requirement for control panel relays that are reliable is still going on.
To satisfy the demand of the OEMs, globally, the relay manufacturers are trying localize their production by opening new regional plants, thereby fueling the relay market expansion. For instance, in 2023, Hongfa Group took the step to set up a fully-owned factory in Germany to provide their customers from Europe with shorter lead times and localize the standards compliance. Part of this expansion is also the enhancement of Hongfa's supply chain in terms of both the challenge of resilience and the advantage of responsiveness. Production localization plays a role in cutting logistic expenses, addressing regional regulatory requirements, and facilitating a faster ramp-up thus making the local markets more accessible and reliable for the wireless industry.
Manufacturers in the relay market are developing relays that are compact, low power, and durable more and more as the demand for energy-efficient home appliances and lighting controls increases. In December 2024, OMRON launched its G5Q HR power relay, which is specifically designed for lighting, smart panels, and home appliances, thus improving the product's endurance and lowering the standby losses. This device allows the appliance OEMs to not only save energy but also lessen the PCB area. By meeting the requirements for efficiency and space, such introductions have the effect of increasing the use of relays in modern appliances and smart home systems all over the world.
