Custom switch solutions, says Molex, can feature value-add design options and fast time-to-market for consumer appliances, industrial equipment and medical devices

These capacitive and metal touch switch solutions offer robust, reliable custom user interfaces. Vertically integrated design and state-of-the-art manufacturing capabilities promise fast time-to-market on custom capacitive and metal switches with a wide range of design options.

Molex custom capacitive and metal touch switches offer immunity to environmental conditions, including resistance to electromagnetic interference (EMI). Available in rigid and flexible substrates including polyester, polyimide and PC boards, the capacitive and metal touch switches offer a range of functional and value-added features including custom backlighting, discrete buttons, linear sliders, and rotary wheels. Designed to IP67-rated specifications, the switch panels offer protection against dirt, water and chemical ingress.

Metal touch switches are pressure activated, which prevents accidental actuation by user error or environmental factors. Fully compatible for use with gloves and styluses, metal touch switches are available with stainless steel, aluminium, and other metallic or non-metallic material overlays, and can feature embossed key or Braille designs.

Capacitive switches recognise when a conductive object, such as a finger, enters the field. Glass, metal and enamel-coated substrates plus tempered-glass, polycarbonate, polyester or acrylic overlays form easy-to-clean capacitive switch designs. Optional Molex PEDOT-based capacitive switches make the transition to one-touch controls more economical and efficient.

These switch solutions have been used in aviation systems, ATM terminals, appliances, fitness equipment, hot tubs, barcode scanners, telecommunications two-way radios, mobile phones, routers and servers, industrial automation equipment, and medical applications including defibrillators, EKG leads, glucose meters, portable oxygen units, infusion pumps and patient monitoring devices.
