Push pull action using LEGO motor

[jismake]

Hello guys

I want to move a solenoid actuator.

I will use this actuator to push a switch every 3 seconds for 35000 times.

I looked at lego motors, but i have not seen a push pull movement.

any good ideas appreciated

thanks

What if you connect the motor to a cam lobe made of LEGO - you can then get a forward / reverse action from one rotational direction (same was a car engine works with a crankshaft and piston rods that move up / down). This could be used to push/pull a switch or simply flip a switch one direction.
