New from Foremost Electronics is a range of short-travel haptic switches which, having the option of an integral LED, are ideally suited to a broad spectrum of switched control applications, such as in an automotive steering wheel which typifies its current use. Introduced as the 3006 Series, from specialist manufacturer Marquardt, they incorporate a snap-action disc within an extremely compact, flat enclosure of 9.85mm square and a profile of only 3.95mm. Though switching travel is a mere 1.1mm, they provide clear tactile feedback, with a switching lifetime better than 0.5 million actions.
Salient operational characteristics include a switching capability of up to 28V at 50mA, and a contact resistance of less than 100mOhm. Incorporating surface mount terminals, they are capable of enduring reflow soldering temperatures at 260oC for 20sec, and are dust-protected to IP50.
Combining their high performance with compact size, attractive appearance and long-term reliability, these haptic switches offer a highly aesthetic solution to a broad range of switching applications demanding extreme touch-sensitivity.
