Abstract
An acceleration sensitive switch for use in detecting an out-of-balance condition on a residential washing machine, or the like, uses a pendulum activated switch wherein the pendulum is biased against an energy absorbing stop by a predetermined threshold force corresponding to the desired switching acceleration. The geometry of the spring and pendulum are such that the restoring force decreases as the pendulum moves to activate the switch providing positive switching action and permitting simple calibration of the unit.
