The range consists of a fully sealed IP67 version with insulated flying leads (500mm length) along with a panel sealed IP67 version which is terminated by a series 16 microswitch. Held in position by a snap fit retaining mechanism, the microswitch has a maximum current rating of 10A and the advantage of SPDT-DB contacts to cover all circuit requirements. Being double break, the contacts also provide reliable switching of DC loads. The Series is available with a choice of round, round with status illumination (flying leads only) or square bezels and with 6 button colour variants. The body and button are made from PBT, a hard wearing thermoplastic polyester that is suitable for surface or sublimation printing or engraving.
