27.09.2024

Challenges in the selection of switches for electrical engineering

Electrical engineering requires precise and reliable components that meet the high demands of modern applications. Companies that rely on high-quality switches and plastic components face the challenge of finding suitable manufacturers that offer quality, innovation and adaptability. This is where PTR HARTMANN's solutions come into play. With a comprehensive portfolio of switches and years of expertise in plastics technology, PTR HARTMANN offers exactly the right products and services to fulfil even the most demanding requirements.

Switch competence centre: Tailor-made solutions for every requirement

PTR HARTMANN is the market leader in the field of rotary coding switches and offers a wide range of standard and customised variants. The switch competence centre bundles the company's know-how, particularly in the development of mechanical switching transitions in the smallest of spaces. This expertise enables the production of highly compact rotary code switches with up to 64 positions as well as unique solutions such as the very narrow thumb wheel switches and dip switches with three switching positions.

Rotary code switches: High reliability and flexibility

The rotary code switches from PTR HARTMANN are characterised by their high reliability and the ability to adapt to different environmental conditions. They offer up to five different switch sizes, various solder pin options such as Through-Hole (THT and THR) and SMT (Gull Wing and J-Hook) and an extra-tight design for extreme ambient temperatures of up to -60°C to +125°C. With their flexibility and adaptability, these switches are ideal for PCBs and other demanding applications.

DIP switches: Precise control and versatility

The DIP switches from PTR HARTMANN offer precise control options with a grid dimension of 1.27 mm and 2.54 mm. With various actuation options such as horizontal, vertical and piano as well as many switch configurations (SPST, SPDT, DPST, DPDT, 3PST, 4PST), they are ideal for flexible and customised solutions. Thanks to the tri-state switching position (+, 0, -), complex switching operations are also possible.

Thump wheel switches: Compact design for customised applications

For applications where space plays a decisive role, the rotary wheel switches from PTR HARTMANN offer a width of just 3.3 mm. With 10, 16 or 32 switching positions and the option of customised printing, they are perfectly suited for use in top-hat rail housings and other space-critical environments. These switches are available both with and without a turntable.

Tact switches: Versatile application options and robust design

The tact switches from PTR HARTMANN offer a wide range of sizes, actuator heights and actuating forces. With horizontal and vertical variants as well as waterproof and ultra-flat switches, they cover a wide range of applications. This flexibility makes them ideal for a wide range of applications in industry and beyond.

Plastics technology: from mould production to series production

At our Baiersdorf site, PTR HARTMANN not only offers expertise in switch production, but also extensive know-how in plastics technology. From the design, construction, maintenance and repair of moulds to the manufacture of assembly devices and initial sample production, the company offers comprehensive solutions.

Development and test laboratory: quality assurance at the highest level

By using 3D simulation processes such as mould flow in the development of injection moulds, PTR HARTMANN ensures that the material flow in the mould is optimal during the injection process. In addition, the company's own test laboratory continuously checks the products through measurements, lifetime and climate tests in order to guarantee the highest quality.

Production: Modern and flexible production sites

PTR HARTMANN's automated assembly lines guarantee 100% control of switch functions through electronic final inspections. The company produces in Germany as well as in Tunisia and China, thus offering global manufacturing capabilities to meet the requirements of its customers worldwide.

Conclusion: Why switches from PTR HARTMANN?

With its comprehensive expertise in the development, production and customisation of switches and plastic components, PTR HARTMANN offers reliable and flexible solutions for every application. The wide product portfolio, the ability to react quickly due to the high level of vertical integration and the worldwide production capacities make PTR HARTMANN the first choice for companies looking for high-quality and customised solutions in electrical engineering.
