# Physical push-down toggle button that pops up on voltage

I have encountered innumerable variations to functionally identical 2-lead physical switches, like the push-to-toggle buttons I am currently working with. Manually depressing the button toggles between two alternate states, popped up and pressed down, each of which physically separates and bring into contact the conductors, respectively.

Does there exist a widely-available 3-lead variation of the described switch that physically pops the switch up when the trigger lead is supplied current, and what it it called?

• Never seen one with 3 leads. 2 leads all the time though. – Ignacio Vazquez-Abrams Dec 20 '14 at 16:03

It has an 11$\Omega$ 5V coil that requires that you limit the on time to 50~100ms maximum on and at least 5 seconds off (2% duty cycle).
