The design and packaging facilitate easy integration into high volume OEM devices. The 14 Series switch is ideal for use in exposed, outdoor environments, such as on multi-function hand-grip joystick heads and handheld robotic controllers. In fields or dirty construction sites where fine dust particles are present, the rugged 14 Series will work every time. This is because of a Dynamic Dust Seal which protects the switch against the ingress of dust even while it is being actuated.
