5278 Series Touchless Switches

The Dortronics Systems Inc. 5278 Series Touchless Switch is engineered with an imbedded optical sensor that picks up motion within a four inch (4”) range of the face plate. If inadvertently touched, the sensor will pick up the motion before actual contact, resulting in normal operation. The switch also features an illuminated LED ring that designates switch status and allows for clear visibility under low light conditions. The LED ring is red during the normal standby mode and green when activated in trigger mode.
