MEC Switches' Multimec 5 series switches are high-performance tactile switches with a wide-range of cap and accessory options
Normally closed/normally open (NC/NO) function means that the switch has an active circuit when not activated and when one pushes the switch, the initial contact breaks and a new contact is made. The function is also known as SPDT – single pole double throw. Having an active circuit when not activated adds the benefit of safety and security. The switch gives feedback to the system that is still operational and able to function when necessary.
