NVIS LED 2014-01-28

 MEC now offers NVIS LEDs for Multimec 5G series switches.

The LED has a filter over it that manipulates the illumination wavelength making it NVIS compatible, which means the illumination is not disturbing one's sight when viewing with night vision goggles. The display conformance for chromaticity and NVIS radiance is per MIL-STD-3009. Other NVIS illumination colours besides green, like white, yellow and red, are also available.

Standard caps and accessories for 5G switches with a total height of at least 11.5mm can be used with the NVIS LED.

NEW function normally closed/normally open 2013-02-07

MEC has launched a new function option for the Multimec 5 series switches: normally closed/normally open.

Not activated

Activated       

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. There is also the benefit of being multifunctional; the switch has three functions:

  1.  NC (make)
  2.  NO (brake)
  3.  NC/NO (switch over; multifunction).

NC/NO 5 series switch has:

  • Life cycles >1.000.000
  • Three standard actuation forces: 2.0N, 3.5N and 6.5N.
  • Sealing IP67
  • Robustness  100N.
  • Low contact resistance <30mΩ
  • Recommended load 0,5-50mA, 24VDC

Multimec 5 series switches are high performance tactile switches with a wide range of cap and accessory options, including many options in shape, size, height, colour, and illumination.
