The TL3780 series tact switch is surface mount and ultraminiature in size. It is a mere 2.0mm x 3.0mm in size with a very low profile of 0.60mm. There are two operating force options: 240 grams and 330 grams. It has a life cycle of 300,000 to 500,000 actuations depending on the operating force, and it has a rating of 20mA @ 15 VDC.
With the small footprint and low profile, and the SMT design, it can be used for many small applications, including wearable technology, medical devices, audio/visual and other products where space is at a premium.
