Get ready to feel like you're on one of network television's hit crime dramas when you pass by and use this new exit switch by SDC.  Scientists, investigators, research assistants, lab techs, hospital staff, and anyone who works in a controlled environment that is used to scrubbing away the germs from touching an exit switch will appreciate this innovative new technology.  To operate the 474 touchless switch, all one has to do is wave their hand in front of the 'No Touch' button.  This will change the contact status on the electric lock, or automatic door opener, making the LED indication light green, which indicates it is safe to enter, or exit. IMPORTANT Activation time is fixed at 5 seconds, and therefore the 474U is most commonly used in conjunction with an automatic door operator (no need to contaminate door or door handle), or an access control system with logic that allows you to set the door unlock time at 30 seconds.
