CUBE SOLID STATE, FLASHER, 1 AMP THKA Timers / Flashers   THKA timers are solid
state output units with digital timing and similar on/off cycle times. The THKA
comes in a 2" square case. Ease of installation and hook-up is a primary design
benefit. All models with integral time adjustment knob or factory-fixed time
require only two connections. They may be wired in-line just like a single pole
switch. Units with external time adjustment have two additional terminals for
the resistor or potentiometer.

Timing Mode
Application of input voltage to the timer starts the “On” time delay. At the
end of the “On” time delay, the “Off” time delay starts. At the end of
the “Off” time delay, the load is again energized, the timer returns to the
“On” time delay, and the cycling continues as long as input voltage is
applied. Removal of the input voltage resets the timer.
