    SMD Push Button Switch

    The SMD type, short for surface mount device, not only saves the installation space, but also improves production efficiency through reflow soldering machine and reel & tape packing. Top push SMD button switch provides more stable handing and mounting stability. The operating life will also be greatly improved.

    Because of the improvement of the production efficiency, the production cost is greatly reduced, so that the tactile switch has became one of the most widely used push button switches.


    Smaller Size & Higher Handle

    Very surprisingly, the ultra miniature tactile button switch, despite its compact size, has an actuator up to 19mm high. The tact switch body can be adapted to narrow space requirements of the design, and the actuated stem can be extended longer. It is a designer’s favorite.


    Multiple Driving Forces Are Available

    There are five operating forces of 100gf,160gf,200gf, 250gf and 300gf to choose from. The designers can select the suitable tact switch according to different application conditions.
