Selectronic’s gapless keypads the way forward for touch response

Selectronic offers gapless keypads for harsh and demanding environments. Consisting of keys bonded to a foil and fixed to the rear PCB via a heat seal, this solution is optimised for compact data entry mats. The company states that a tactile switch action gives the operator good clear haptic response and excellent key top finish.

To enhance the user feedback, metal domes can also be added to the gapless design proposal to maximise the ‘haptic feedback’.  This feature is particularly applicable when keypads are being operated with a gloved hand in harsh environments and it is also said to ensure feedback to the operator.

“Where this is not required, or if price is a bigger concern, the metal dome can be replaced with a low resistance carbon pill (LRCP) to provide the electrical function,” said Kevin Dry, managing director, Selectronic. “As with all keypads from Selectronic, sharp edged laser etched engraving is available to provide the sharpest of images for the icons on the surface of the pad and this can be combined with optimised LED lighting to provide the very best backlight performance. Gapless keymats can bring a new modern look to a keypad and offer the opportunity to bring a new overall appearance to your brand.”

The one piece top surface linked to gapless also offers dust and debris resistance and, with the options for hard coating, a long product life can be secured with keytop markings maintaining their integrity over the full life of your product.

“Cost savings associated with easy assemble can also be realised or by talking to our engineering team the option for a complete one piece top moulding is available,” added Dry. “Keypad design is always an area where smooth operation combined with exceptional reliability and long life can be achieved by our Selectronic team who really understand the options and how best to configure a great switching product.”

Selectronic offers a variety of products, including mobile keypads, cover glass, complete modules, automotive parts and lighting modules.
