Robust panel-mount illuminated switches feature IP67 waterproof rating


W48M series from Lumex are 19 mm switches in five color options and with three choices of indicator symbol

The Lumex W48M illuminated push-button switches offer a variety of options for color and indication symbol.

These 19 mm panel-mount switches are available with either a halo, ring, or standby power logo indicator symbol. Color options are green, blue, red, white, or yellow.


The electrical configuration is normally open, with a single pole, single throw mechanism. The switch action may be momentary or maintained. The W48M switches have a metal housing and bezel.


The switches have an IP67 waterproof rating. Versions with a wire lead harness can also be specified with bottom sealing: this increases the force required to pull the switch out of its mounting, and makes the device suitable for use in harsh environments. The switch can also be supplied with high impact resistance.


The W48M switches are available in versions with no LED illumination.
