Capacitive touch switches are vandal-resistant for medical use

Rugged, capacitive touch switches, launched by Bulgin, are rugged and designed for repetitive operation. The sealed IP68-rated switches are activated by the touch of a finger and can be used across a wide range of applications from heavy industrial to consumer appliances.

The switches do not feature any moving parts and they require no operating force to activate. These characteristics offer both ease of use and a long life expectancy of up to 50 million operation cycles, explains Bulgin. They are robust and durable in design, being both dust- and water-resistant and are also vandal resistant.

The switches feature an auto-calibration function, enabling them to adapt to their external environments, and support both momentary and latching operations.

The capacitive switches are available in 16, 19, 22 or 25mm diameter sizes and are offered in a choice of anodised black, red or natural colours as well as 316L stainless steel. Customers also have a large variety of ring illumination options from which to choose.

The range of capacitive switches are easy to clean, says Bulgin, and are robust and sensitive, making touch activation possible even where the user may be wearing surgeon’s gloves, says Christian Taylor, engineering team leader at Bulgin. The switches meet the needs of a diverse selection of applications, from medical and laboratory equipment and food processing machinery to consumer applications such as appliances, vending machines and lift controls.

The capacitive switch range joins Bulgin’s portfolio of pushbutton, piezo, slide, toggle and rocker switches designed for a wide variety of industry applications.

Bulgin manufactures a range of industry-leading rugged connectors, fuse holders, battery holders, switches and indicators designed for use in challenging environments. Headquartered in Cambridge, UK, Bulgin has offices and a sales and distribution network spanning 65 countries. Its manufacturing facilities are based in the UK and Tunisia.
