Frequently Asked Questions
Which switches is this compatible with?
It's designed to clip onto EMAS's CP and CM series pushbuttons, selectors, e-stops, and joysticks — the same 22mm control unit range used throughout the CP product line.
Do I need any tools to fit it?
No — it clips into place on the back of the switch body without special tooling.
What's the difference between C1 and C2?
C2 is normally-closed (N.C.) — the contact opens when the switch is actuated. C1 is normally-open (N.O.) — the contact closes when actuated. Use C2 for stop or safety-interlock functions, and C1 for start functions or extra signalling.
Can I use this to add a second channel to my e-stop circuit?
Yes — a C2 block is the standard way to add a second N.C. contact to an EMAS e-stop for dual-channel safety relay wiring.
Industry Applications
- Machine safety circuits — adding a second N.C. channel to an emergency stop for dual-channel safety relays
- Motor control circuits — adding auxiliary stop signalling to an existing switch
- Panel refurbishment & repair — replacing worn contact blocks on existing EMAS CP/CM series switches
