Space-saving pushbutton TACT switch for portable products

16 May 2007 Switches, Relays & Keypads

knitter-switch has introduced its TSS 309 pushbutton tact switch designed for a variety of mobile and portable product applications.

This space-saving surface mounted switch measures 3,8 x 6,0 mm with a height off the board of just 1,7 mm. For secure mounting and good electrical contact, knitter-switch has incorporated a single J-lead terminal to ensure maximum solder on the joint and easy visual inspection. Where required, versions can be provided with flat solder terminals.

Two actuator forces are available, 180 and 360 g and operational lifetime is better than 100 000 operations. The TSS 309 may be soldered at 260°C, is RoHS compliant and features contact ratings of 12 or 23 V d.c. @ 50 mA, a maximum contact resistance of 100 mΩ and an operating temperature range of -20 to 70°C.
