Finder has updated and extended its 12 Series of 16A time switches, commonly used in a range of lighting, heating and ventilation applications. Comprising mechanical and digital daily and weekly time switches, the 12 Series has been completely redesigned to increase the number of switching points and minimum interval settings and to improve the man-machine interface.

With all 12 Series time switches now enabling direct switching of lighting loads up to 2000W and AC1 loads up to 4000VA, they also significantly reduce the need for additional slave switching components.

Added to the mechanical time switch range, the 12.31 is Finder's first to be offered in a 72mm square front panel mounted housing. Providing a large visible timing dial, it offers users easier access and simpler daily or weekly programming. The device complements the space saving, 35mm rail mounted 12.01 and 12.11 daily time switches.
The 12.21 and 12.22 digital weekly time switches have also undergone a significant face-lift. Now equipped with a much larger 'wide screen' LCD display panel and bigger and more tactile push buttons, the time switches make programming a far more intuitive task. Single and double pole output versions respectively, the time switches offer users an impulse output function and automatic winter/summer time adjustment.

New to the 12 Series, the 12.91 and 12.92 digital weekly time switches provide an 'astro' programming capability enabling switching according to local sunrise and sunset times, calculated automatically from current date, time and either local longitude and latitude or nearest major city. The timers support up to 60 on/off output switching events, programmable to the nearest minute and impulse outputs programmable from 1 second through to 59 minutes 59 seconds.
