ABSTRACT:
The present invention is a knob which attaches to the switch post of a push/pull switch. The knob selectively disengages from the switch post as the knob is inadvertently impacted, thereby isolating the push/pull switch from the impacting force. The knob moves independently of the switch post and contacts the housing supporting the switch. Consequently, the force of impact is directed to the housing through the body of the knob and very little force is directed to the switch.
