Expanded Switch Portfolio with Robust BCK and BCKS Rotary Coding Switches for Versatile Applications

Electromechanics I 05.10.2026
We are further expanding our cooperation with British switch manufacturer Lorlin Electronics and are now its official distribution partner in Germany. As part of this partnership, we have significantly expanded our Lorlin portfolio and now offer around 140 products from the manufacturer. This gives our customers access to a broader range of switch solutions for a wide variety of applications.
New additions include the BCK and BCKS series binary-coded rotary switches. They are available in hexadecimal-coded and complementary versions and feature adjustable stops that allow the number of switching positions to be limited. The BCKS series additionally features a front-panel O-ring seal rated to IP66/IP67, making it suitable for applications with increased requirements for protection against external influences.
Both series feature a 22.5° indexing angle as standard and are rated for switching currents of up to 150 mA at 24 V AC/DC. They offer a mechanical service life of more than 10,000 switching cycles and can operate within a temperature range of −30 °C to +85 °C. The initial contact resistance is less than 50 mΩ, while the insulation resistance is greater than 999 MΩ at 500 V DC.
Depending on the version, different spindle options are available, including flat, slotted and knurled designs. Silver contacts are fitted as standard, while gold-plated or gold-flashed contacts are available as alternatives. The housing is made of glass-fiber-reinforced polyamide 6.6, with a version made from UL V-0 rated material available as an option. PCB terminals with additional locating lugs are provided for PCB mounting.
