Controlled sourse by a control signal

Hi,

I try to design a square wave oscilator. To do this,i need to commute two current sources (positive and negative). Is there in simulink any block like a current generator controlled by a control signal?. I mean, if the control signal value is '0' the generator is off, and if the control signal value is '1' the generator is on. If isn't exist this kind of block, any idea what can i do that?

Thanks in advance. Néstor

You can use a switch block
