The AS series of subminiature slide switches from NKK Switches is about one-third the size of conventional miniature switches. Designed for logic-level applications, the AS series slide switches are rated for 0.4VA at 28Vac/dc maximum.

Several mounting options are available including straight PC in bracketed and unbracketed versions, as well as vertical and right-angle mounts. All terminals are molded in, epoxy sealed and ultrasonically welded to lock out flux and other contaminants.

Terminal spacing is 0.100-by-0.100 inch and conforms to standard PCB grid spacing. Wave soldering is recommended for these devices. The slide switches are not process sealed. Matching indicators with LEDs in red, green and amber can also be ordered.

The AS slide switches feature NKK's Sliding Twin Crossbar (STC) contact mechanism. The STC contact design offers benefits unavailable in typical mechanisms, including smoother positive detent actuation, increased contact stability and high logic level reliability, according to the company.

These slide-actuated devices are constructed with an anti-static superstructure of carbon-blended polyacetal that prevents static discharge to the contacts when used with the support bracket options. The AS slide switches can be configured with various actuator lengths and in single- or double-pole circuits.

The AS series is priced at $1.70 per piece in quantities of 1,000. Delivery is from stock to six weeks.
