Knitter-switch manufactures a range of membrane keypads, rubber keypads and complete units with touch screens.
The membrane keypads are available in flat, poly-domed and metal-domed types, giving a variety of levels of tactile feedback and life expectancy in excess of one million operations. They are tested for resistance to surface scratching, thermal shock, electrical ratings and operating lifetime.
The membrane keypads are provided with a graphic overlay only or full switching membrane. They offer ESD/RFI shielding and provide for insertable legends.
Silicone rubber keypads are manufactured from elastic, non-toxic silicone rubber compounds and formed by compression or injection moulding. The result is an economic and reliable keypad for small, medium and large production runs. Silicone keypads can be integrated with printed circuit boards or flexible circuits and have excellent resistance to temperature and ageing.
Touch screens are available with resistive or capacitive principles as complete customised functional units integrated in modules such as front panels.
