1. A swing training device comprising:
- an axial force sensor including a first set of electrical contacts, said axial sensor operative to change the state of said first set of contacts when a predetermined axial force is exceeded;
a lateral force sensor including a second set of electrical contacts, said lateral sensor operative to change the state of said second set of contacts when a predetermined lateral force is exceeded;
an electrically actuated signalling device; and
a source of electrical energy disposed in electrical communication with said signalling device, said first set of contacts and said second set of contacts, and means for actuating said signalling device when said predetermined lateral force is exceeded and said predetermined axial force is not exceeded.

Abstract
A golf swing trainer includes a sensor responsive to axial forces and a sensor responsive to lateral forces disposed in electrical communication with an alarm circuit. The training device is responsive to velocity and attitude of the golf club and is operative to provide a user-detectable signal if an improper swing is executed. An alarm is actuated when a predetermined lateral force is exceeded and a predetermined axial force is not exceeded.

20. A golf swing training device comprising:
-
I. an axial force sensor, said sensor including; a first, generally elongated shaft; a support bearing disposed to retain said first shaft and to allow for the lengthwise displacement thereof; a first contact block; and a spring disposed to bias a first end of said first shaft into contact with said first contact block; II. a lateral force sensor including a second, generally elongated shaft aligned along a common linear axis with said first shaft; a spring member disposed to interconnect a first end of said first shaft to a first end of said second shaft; a second and third contact block disposed on opposite sides of said second shaft proximate a second end thereof; a weight disposed on the second end of the second shaft; III. a signalling circuit disposed in a series electric relationship with said first contact block, said first shaft, said spring, said second shaft and said second and third contact blocks, said signalling circuit including a source of electrical power and a signalling device and means for actuating said signalling device when said predetermined lateral force is exceeded and said predetermined axial force is not exceeded.
