1. A force sensor mountable on an outside lateral surface of a golf club grip comprising:
a base member having a substratum with a substratum inner face and a substratum outer face and a projection on said substratum outer face having a projection height, wherein said base member has a relatively high resistance to elastic compressive deformation when a manual grasping force is applied to said base member during a golf swing; and
an overlying member positioned atop said base member and having an overlying member inner face, an overlying member outer face and a channel extending from said overlying member inner face to said overlying member outer face and configured to receive said projection in a channel interior, wherein said overlying member has an overlying member thickness with an ambient thickness value greater than said projection height when said overlying member is in an ambient state, and wherein said overlying member has a relatively low resistance to elastic compressive deformation, thereby reducing said overlying member thickness to a compressed thickness value less than said projection height when a manual grasping force exceeding a maximum permissible force value is applied to said overlying member during the golf swing and extending said projection out from said channel interior beyond said overlying member outer face.
