Multimec® 5 series switches
normally closed/normally open function
Normally closed/normally open (NC/
NO) function to the Multimec® 5 series
switches means that contact is established
when not activated. When the switch is
activated it breaks the contact and makes
a new contact.
The switch has three functions:
• NC (makes)
• NO (brakes)
• NC/NO (switch over, also known as
SPDT - single pole double throw).
Application - NURSE CALL SYSTEM
The advantage of using the NC/NO function switch is that the system all the time
”knows” that the connection to the nurse
call system is still in place and working.
Application - PUSH-TO-TALK HEADSET
NC/NO function switch simplifies the
change between a speaker (headset) and
microphone unit. The headset is working
when switch is not activated and when
pressing the switch, one breaks the signal
and the microphone turns on.
