The switches used in Logitech Silent Mice are made of a rubber actuator that dampens both the vibration and the sound. A red plastic cap covers the rubber actuator to improve the switch's tactile feedback and lengthen its lifespan.
Logitech 2.4 GHz Digital Cordless for Business features frequency agility. With this technology, the Logitech mouse or keyboard that encounters any interference from another cordless device will automatically identify and switch to a more “quiet” location in the band to transmit data.
Waterproof means that the device is not adversely affected by contact with water and can withstand water contact without becoming damaged.
