ITW Switches offers a unique series of panel-sealed pushbutton switches designed to handle demanding, harsh environments. This versatile series features a basic switch element that snaps in behind the button so that designers can specify a single-pole or double-pole switch behind the same sealed pushbutton.
Available with three button colours (red, green, black), the Series 49-59 sealed pushbutton switches are well suited for applications such as communications, instrumentation, data processing, military environments, environmentally demanding keypads, and mass transport controls.
These switches are offered with a choice of round or square bezels. Bodies and buttons are made from PBT (polybutylene terephthalate), a hard-wearing thermoplastic polyester suitable for surface or sublimation printing or engraving. PBT also is flame-retardant and UL-rated. Other features include a wide temperature range - up to 105°C - and an industrial standard 16,0 mm panel cut out size. The switches carry the IP67 immersion rating and exceed NEMA 4X.
The 49-59 pushbuttons provide momentary action, and connections are made via solder terminals at the rear of the switch. The snap-in switch elements feature silver or gold contacts with current-carrying capacities up to 10 A. Exact current ratings are (silver contacts) from 3 A at 28 V d.c. to 10 A at 125 V a.c. and (enhanced gold contacts) from 8 A at 28 V d.c. to 6 A at 115 V a.c.
