NKK Switches Announces Ultra-Miniature Two and Three Position Slide Switches

SS Series ideal for high-density PCB and SMT mounting

SCOTTSDALE, Ariz. - NKK Switches, the world's leading designer and manufacturer of innovative electromechanical switches, today announced the availability of the SS Series of ultra-miniature slide switches. The series' compact dimensions and low profile make it a preferred choice for designs requiring high-density PCB or SMT mounting.

The series was specifically designed for logic level applications and each device features NKK's award winning STC (Sliding Twin Crossbar) contact mechanism. This mechanism provides benefits unavailable in conventional mechanisms, including smoother positive detent actuation, increased contact reliability and unparalleled logic level switching reliability. Crisp actuation positively indicates circuit status.

In addition, the SS Series is configurable with top or side actuation in single and double poles, and with two and three throw options, permitting engineers even greater design flexibility when faced with demanding applications. Low profile and compact dimensions allow for high density mounting and close stacking on PC boards.

The terminals are insert-molded to lock out flux, solvents and other contaminants, and the contacts self-clean with each actuation.

Electrical ratings are 0.1A at 30V DC with silver contacts, and 0.4VA at 28V AC/DC with gold contacts. SPDT, SP3T, and DPDT circuit configurations are available and all circuit options are maintained.

Single pole and double pole models are available with either inch or metric terminal spacing for standard PC board grid mounting (.100" x .100" or 2.0mm x 2.0mm).

Surface mount versions are available in single pole, double throw and single pole, three throw options and are packaged 500 pieces per tape/reel. Tape/reel packaging meets the EIA-481-2 Standard. Alternative tray packaging is available upon request.

In addition, surface mount models are made with heat resistant resin, allowing for vapor phase and infrared reflow soldering which translates to time and labor savings. The double molded thermoset base and thermoplastic housing for through-hole models are rated at are rated UL 94V-0 for flammability and prevent loosening of terminals due to high soldering temperatures. Surface mount models also feature gull wing terminals, which ensure mechanical stability and simplify solder joint inspection.
