Abstract
An accelerometer switch which has cantilever beams carrying integral end masses formed in a silicon die which is sandwiched between a contact plate and a support plate. Each beam provides switching at a different threshold acceleration level. The fixed contact face of the contact plate is configured with a relief space to permit accelerometer switch operation even though the input acceleration is off-normal and there is twisting of the accelerometer beam.
