Micro-Miniature Pushbutton Switches From knitter-switch Are Just 1.48mm High

One of Europe’s leading switch manufacturers, knitter-switch, introduces a very small, tactile, pushbutton switch that will find many applications in all types of handheld devices including PDA’s and those designed for medical and industrial use.

According to knitter-switch, these tiny switches are ideal for those functions in a handheld device for which a touch-screen or sensor button is not suitable. These include stand-by switch, volume adjustment, keypad lock and camera shutter functions.

Measuring just 3.8 x 2.8 x 1.48mm, the knitter-switch TSS 5400 series includes models that can be vertically or horizontally actuated. Operating actuation force is 160gf for vertically operated switches and 200gf for horizontal types. Contact rating is 50mA, 12VDC, electrical life is 100,000 cycles and the terminals are silver plate over nickel. The switch cover is silver plated stainless steel and the base is high-temperature thermoplastic.

Switches in the new TSS 5400 series are Halogen free and are available with the option of gold-plated contacts. All models have an operating temperature range of -40 to +85ºC.

Standard switches are available from a number of distributors throughout Europe. Samples are usually available on next day delivery.
