The S-Click HNS410TM is a 2-in-1 lighting timer switch that automatically turns lights off after a pre-determined time. Time delay can be set in minute increments from 1-60 minutes - perfect for areas that are frequently occupied for relatively short periods. Supporting both timer and non-timer functions, this unit also allows for lights to be manually turned off with a quick tap. Our minute timer switch is ideal for domestic use and can be retrofitted to most installed lights. A blue LED indicates device status and gives an expiry warning within the last 10 seconds before the lights time-out. The timer settings are retained even after loss of power and can be configured to power up on or off after loss of mains power. Programming your chosen off time couldn't be simpler. A sustained 10 second press of the button enters programming mode. Just tap the button once for each minute of run time you require, up to 60 minutes. Programming mode expires 10 seconds after the last tap, and the unit then commits your settings to memory. If you happen to press the button more than 60 times, the maximum run time of 60 minutes will be stored.
