In 2022, C&K (formerly C&K Components) underwent its most significant corporate transformation in decades when it was acquired by Littelfuse, Inc. for approximately $540 million. This transition moved the high-performance electromechanical switch manufacturer from private equity ownership under Sun Capital Partners to becoming a cornerstone of Littelfuse’s expanded electronics segment.
The State of C&K at the Start of 2022
C&K entered 2022 as a global leader in the design and manufacture of high-reliability electromechanical switches and interconnect solutions. With a history stretching back to 1928, the company had established a reputation for precision engineering, particularly in the "tactile switch" market. At the dawn of 2022, C&K was headquartered in Waltham, Massachusetts, and operated major manufacturing hubs in France, Germany, Vietnam, and China.
The company's position in the market was defined by its "Hi-Rel" (High Reliability) components. Unlike consumer-grade switches found in cheap peripherals, C&K’s products were engineered for millions of actuations, extreme temperature resistance, and precise haptic feedback. This made them indispensable to the automotive, industrial, medical, and aerospace sectors. Throughout the first quarter of 2022, C&K continued to innovate, focusing heavily on miniaturization to meet the demands of wearable technology and the increasing complexity of medical devices.
The ownership by Sun Capital Partners, which began in 2017, had focused on operational improvements and market expansion. By early 2022, C&K had achieved an annual sales volume of approximately $200 million. This financial health and technical prowess made it a prime target for strategic acquisition by a larger industrial entity looking to bolster its electronic component portfolio.
The 2022 Acquisition: Littelfuse and the Strategic Shift
The defining event of the 2022 C&K timeline was the acquisition by Littelfuse, Inc. (NASDAQ: LFUS). This move was not merely a change in ownership but a strategic alignment that signaled a shift in the broader electronics industry toward integrated solution providers.
The Financial and Strategic Agreement
On May 13, 2022, Littelfuse announced that it had entered into a definitive agreement to acquire C&K. The transaction was valued at an enterprise value of $540 million, subject to customary working capital and net debt adjustments. For Littelfuse, the acquisition was a logical expansion. While Littelfuse was already a powerhouse in circuit protection, power control, and sensing, the addition of C&K provided a "front-end" interface to their existing "back-end" protection components.
The strategic rationale was built on three pillars:
- Market Diversification: C&K’s strong presence in the industrial and medical markets complemented Littelfuse’s existing footprint.
- Cross-Selling Opportunities: Littelfuse could now offer a more complete bill of materials (BOM) to its customers, combining switches with sensors and fuses.
- Technological Synergy: C&K’s expertise in haptics and miniaturized electromechanical systems integrated well with Littelfuse’s sensing technologies.
Closing the Deal
The acquisition moved rapidly. On July 19, 2022, Littelfuse officially announced the closing of the acquisition. From this point forward, C&K began its integration into the Littelfuse Electronics Business Unit. The transition involved aligning global distribution networks and merging sales forces to provide a unified face to major automotive and industrial OEMs (Original Equipment Manufacturers).

Technical Evolution and Product Focus in 2022
Despite the corporate upheaval, C&K’s engineering department remained highly active in 2022. The year saw a push toward "smart" switches and extreme miniaturization.
Miniaturization and the NanoT Series
One of the most significant technical achievements for C&K in 2022 was the commercialization of the NanoT series. These were the smallest tactile switches in the world at the time, designed for the "hearables" market (hearing aids, earbuds) and advanced medical devices. The NanoT featured a top-actuated or side-actuated design that occupied minimal PCB (Printed Circuit Board) real estate, which is a critical requirement in 2026’s even smaller wearable devices.
Automotive Haptics
In 2022, the automotive industry was pivoting hard toward Electric Vehicles (EVs) and sophisticated digital cockpits. C&K capitalized on this by expanding its KSC series tactile switches, which are known for their customizable sound and feel. As car manufacturers moved away from bulky mechanical levers to sleek, integrated consoles, the demand for C&K’s precision switches increased. These components provided the "premium" tactile click that consumers associate with high-end vehicle interfaces.
Medical Grade Reliability
The COVID-19 pandemic had accelerated the need for reliable medical hardware, a trend that continued into 2022. C&K’s switches were integrated into ventilators, infusion pumps, and surgical tools. The 2022 roadmap focused on enhancing the ingress protection (IP) ratings of their switch lines, ensuring they could withstand the harsh sterilization chemicals and fluids common in medical environments.
Integration Challenges and Outcomes
The merger of a specialized switch maker into a broad-line component manufacturer like Littelfuse presented unique challenges in late 2022. C&K had a highly specialized sales force that understood the nuances of "haptic feel" and "actuation force"—concepts that were somewhat different from the "current ratings" and "voltage drops" focused on by the traditional Littelfuse team.
To resolve this, Littelfuse maintained much of the C&K specialized engineering support. This ensured that customers who relied on C&K for custom-tailored switch solutions did not experience a drop in service quality. By the end of 2022, the transition was largely considered a success by market analysts, as Littelfuse reported that the integration was ahead of schedule and the C&K brand was performing well within the larger corporate structure.

The Role of Sun Capital Partners (2017–2022)
To understand the 2022 overview, one must look at the role of Sun Capital Partners, the private equity firm that sold C&K to Littelfuse. Sun Capital acquired C&K in 2017. Over the five-year period leading up to 2022, Sun Capital invested heavily in C&K’s manufacturing automation and expanded its footprint in the Asian market.
The 2022 exit for Sun Capital represented a significant return on investment. By streamlining the manufacturing processes in Vietnam and China and focusing on high-margin niches (like aerospace and medical), Sun Capital increased the company's valuation. When Littelfuse stepped in, they were purchasing a leaner, more profitable company than the one Sun Capital had originally acquired. This historical context explains why the 2022 valuation was as high as $540 million, a figure that reflected both current earnings and future growth potential in the EV and IoT sectors.
Industry Impact: A Consolidated Landscape
The 2022 acquisition was part of a larger trend of consolidation in the electronics component industry. Smaller, specialized manufacturers were increasingly being absorbed by "one-stop-shop" giants. This consolidation was driven by the global supply chain crisis of 2021-2022. Large OEMs began to prefer working with fewer, larger suppliers who had the financial muscle to secure raw materials and manage global logistics.
For the engineering community, the 2022 C&K transition meant:
- Easier Procurement: Accessing switches, fuses, and sensors through a single Littelfuse representative.
- Unified Support: A broader network of Field Application Engineers (FAEs) who could assist with complex designs.
- Enhanced Stability: The backing of a multi-billion dollar corporation ensured that C&K’s product roadmaps were financially secure for years to come.
The acquisition was documented as a key growth driver in the Littelfuse Q3 2022 Earnings Release, which highlighted the immediate revenue contribution from the C&K product lines.
