Product Details

The NS-1 is a simple on-off toggle switch mounted in a convenient plastic case. The NS-1 can be used with Viking products that have a “Night Switch” input or any product that requires an external switch closure. The compact design and foam mounting tape make it easy to install the NS-1 almost anywhere – right next to the equipment in a phone closet or remotely at a front desk. The NS-1 has 24” wires and comes with two quick connectors.
