I have a battery operated digital timer circuit board that will control a small motor, via a control board. The timer runs on 3.6vdc (batteries). The timers Output Control Signal is 3.6vdc when on, and 0Vdc when off. The timer is replacing an old analogue timer. The old timer had normally open switch contacts. I think that I will need a transistor to act as a switch, can anyone recommend a transistor and resistor (if needed) that would be suitable for this scenario?
