Changing control module

I have a ceiling fan that was controlled by an on and off rocker switch. I unistalled the current switch and noticed it only had two black wires connected and no space for a ground wire. The new switch has the two black wires and a ground wire. Is it possible that the switch I unistalled is grounded another way? I capped off the ground wire on the new switch and conected the two black ones and I am wondering if that sounds right? The new switch does work fine, but I was just concerned about the grounding of the new switch.

Grounding of switches

Switches that are mounted to a yoke or strap, and designed to be mounted in a device box or box ring, need only be bonded to the Equipment Grounding Conductor (EGC) when they are mounted in palstic boxes or device rings. If they are mouted in a metal box or to a metal device ring that is attached to a metal box then all that is necessary is to make sure that the box itself is bonded to the EGC. The reason for grounding the yoke or strap of a snap switch is to gaurd against the possibility of a fault to a metallic wall plate that is installed by attachment to the yoke or strap. The Code Mking Panel's position on the issue so far has been that the ordinary mounting screws provide sufficient bonding for the degree of risk associated with a fault to the cover plate of the device.
