Hi All, I need to turn ON or OFF a small 12V d.c. motor using a micro-switch, but= =20 the requirement is, the micro-switch must be operating like a toggle swit= ch,=20 i.e. when the micro-switch is pushed (and released immediately) once, the= =20 motor will be turned ON, it will remain ON and will only be turned OFF wh= en=20 the micro-switch is pushed (and released) again. I know a micro-switch alone will not be able to do this, I may need some=20 relays or other components working together to achieve this, but I don't=20 want complicated circuits that require a stable power supply, I just want= to=20 use some simple passive components (and relays) to do this. I would appreciate if any one could suggest such a circuit or method. Thanks in advance.
