The CB7 is a clip-on blue LED illumination block that turns any CP or CM series pushbutton or switch into a backlit control, without needing a separate indicator lamp. Blue is commonly reserved for a specific function like reset, distinct from the more common run/stop colours — a useful way to backlight a control that shouldn't be confused with routine buttons. It clips on without tools and is held in UK stock for fast dispatch.
Technical Details
Frequently Asked Questions
Which switches does this fit?
It clips onto EMAS's CP and CM series pushbuttons and switches, adding LED backlighting to units that weren't originally illuminated.
What voltage does it need?
12-30V AC/DC, suited to PLC and relay-driven low-voltage circuits.
What's blue typically used for on a control panel?
Blue is conventionally reserved for a specific, deliberate function such as "reset," distinct from the general start (green) and stop (red) colours.
Can I add this to a switch I've already installed?
Yes — it's designed as a clip-on retrofit, so you don't need to replace the whole switch to add backlighting.
Industry Applications
- Manufacturing control panels — backlighting a reset function distinct from primary start/stop controls
- Panel upgrades — adding visual confirmation to previously unlit reset or special-function controls
- Machine safety circuits — clearly distinguishing a reset button after a fault or e-stop event
