IP68 tactile switches

11 May 2011 Switches, Relays & Keypads

C&K Components has upgraded its KMT0 series of miniature tactile switches to provide IP68 sealing. The switches are completely sealed and stay fully functional under water for a minimum of 5 hours at a depth of 2 metres. In addition, the KMT0 series is fully resistant to the most stringent conformal polymer coatings, including one of the smallest particle chemical vapours, parylene, which is used for coating printed circuit boards (PCBs) and medical devices.

Featuring a lifespan of more than 300 000 electrical and mechanical cycles, the KMT0 series tactile switch’s low profile makes it a viable solution for handheld and portable electronic device applications that require a small footprint, while the IP sealing provides protection against perspiration and water in portable devices.

The RoHS-compliant and halogen-free ultra-miniature KMT0 switches feature a footprint of 3,0 x 2,6 mm with a height of 0,63 or 0,65 mm. The SPST (single pole single throw) normally-open switches are constructed with silver plating and are available with four operating forces: 1,0 N, 1,6 N, 2,3 N and 3,4 N. Maximum overload is 30 N. Actuator height is only 0,2 mm, and the integrated actuator allows for simpler button design while yielding a tactile ratio minimum of 30%, providing sharp feedback (low tactile ratio of 10% is available for hearing aids and headsets).

The switches feature a maximum power rating of 0,5 VA and a minimum/maximum voltage of 20 mV – 32 V d.c. with a minimum/maximum current rating of 1 mA–50 mA. The operating temperature ranges from -40°C to +85°C.
