Hello guys am a new member here, and would like to receive some help. Am working on a printing machine project in which I have to use transistor switching circuit with an input of 24volts dc to switch on/off an actuator of 24v dc by means of a switch. Can anyone help me out with a circuit diagram?

 

Can you just wire the switch in series with the actuator? If not, why not?

Is this homework? If so, it should have been posted in the Homework Forum.

 

No it's not a homework assignment please. Am incorporating my design into a paper folding machine after the original electronic card controlling a knife blown up. Am using a paper sensor to control the actuator, but the load of the actuator will likely blow the sensor up. I used a 24v dc relay to do the power switching, but it's not switching fast enough because the machine is a high speed machine. That's why I want to use transistor switching instead to control the actuator.

 

What current are you switching? How many amps.
What kind of load? Motor, solenoid, heater?
What sort of sensor are you using to control this switch?
Exactly how fast does it need to switch?

 

A MOSFET will probably be part of the solution, but we need answers to the questions in post #4.
