    Hi there,
    I'm trying to build a circuit in workbench which requires a push switch, but I cant find it anywhere! Is there an external libary or somthing?

    Basically I'm trying to make the coin tosser circuit which generates pulses with 555 timer which then go two a 7473.

    Any help would be much appreciated,
    Matt

    I don't use EWB, but most simulators have a voltage-controlled switch (VCS). I use LTspice (SwitcherCAD III) from Linear Technology. Their VCS is somewhat of a pain in the ass, because you have to create a .model directive for the switch every time you use one. Maybe all versions of Spice have this requirement. It certainly beats not having a switch at all.
