Title: Shock absorbent roller thumb wheel
Inventor: MA DAVE M
IPC: H01H19/58
Filed: 2003-04-09
Abstract: A shock absorbing roller thumb wheel is disclosed. The shock absorbing thumb wheel includes a central hub that can be secured to an electro-mechanical switch, a rim encircling the central hub, and force dispersion spokes extending from the central hub and connected to the rim. The configuration of the force dispersion spokes and the resilient material of the force dispersion spokes and the rim allow for radial and lateral deflection of the rim in response to an applied impact force. The impact force is thereby at least partially absorbed by the radial and lateral deflection of the rim and spokes, such that less impact force is transferred to connections between the electro-mechanical switch and any assembly to which the switch is attached. Hence, the probability of connection failures is reduced, and the lifetime of a device that uses the thumb wheel can be extended.
