Miniature Delay On Make Timers
TBC Miniature Timers

TBC timers are solid-state output units with digital timing and come in a 15/8" 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 three connections.

Timing Mode

Application of input voltage to the timer starts the time delay. At the end of the delay period, the load is energized. To reset, remove the input voltage to the timer.
