Servo Motors Activated by a Float Switch

Thread Starter

I have a float switch and two servo motors. The float switch allows a max current of 1 Amp, while the motor has an operating range of 4.2-6V. I am either going to use both motors in parallel or just one. Either way, I want the motor(s) to be activated when the switch is on. With a power source of about 4.8V, will I draw too much current for the switch? Or do I need a relay?

The operating voltage of a motor says nothing about the current.
What type ans size of motors are they?
Is there a brand and type plate?

How are you generating the servo pulse train?
Some mor detail of what you are actually trying to do would help.
Are you just trying to start and stop a couple of motors or actually drive servos to a desired position?
What else is there besides a switch and a couple of servos?
