Key Card Switches

Key Card Switches

These wireless, self-powered transmitters are designed to accept room or security card keys as used in hotel rooms, boarding rooms and offices. Key card switches ensure that lights are turned off when the occupant leaves. Energy harvesting is made via a maintenance-free energy generator. This product is directly commissioned from Niagara using thecns-enocean Connectivity Kit.

Key Features

The Key Card Switch is one of the simplest, most economical ways to save energy through occupancy based control of lighting, HVAC and miscellaneous electric loads. To operate the switch, users such as guests simply insert their key card in the slot when they enter the room and then remove it when they leave. The switch is self-powered and the simple act of inserting or removing the card generates enough kinetic energy to send a wireless signal to other EnOcean-based devices within the room. Additionally, the key card switch is wireless and can be installed in minutes without having to drill into the wall or run additional wiring.

  • Determine Occupancy

    The Key Card Switch determines occupancy based on the key card being inserted or removed, which, once triggered transmits room occupancy status wirelessly to other energy saving devices/EnOcean devices in the room. Thus, this enables other devices to minimize energy use whenever the room is unoccupied

  • Wireless and Battery less

    The wireless, self-powered device eliminates the need for additional wiring and batteries, which allows for easy installation in new or existing rooms, subsequently reducing operating costs.

  • Flexible

    This energy harvesting wireless solution provides limitless supplies of energy and unrivalled flexibility, kinetic energy is harvested from the card action, making the device battery less and environmentally friendly.

  • Cost Effective

    The Key Card Switch is ultimately an affordable and convenient occupancy based solution for controlling lights, HVAC energy use, and other electrical loads. The slot itself also accommodates any standard hotel key card.
