A waterproof switch has a single contact arranged in a sealed housing, with an actuator arm protruding from one end and electrical terminals protruding from an opposite end. The single contact is arranged close to a metal portion that is moved by the actuator into mechanical and electrical contact with the single contact. The sealed housing is formed of two pieces that are attached by a heat activated adhesive. The switch can be assembled by forming the metal switch parts on a long strip and subsequently, following the assembly of the housing, the small metal portions joining the switch parts are sheared away.

A sensor of Giant magneto-resistive (GMR) type is attached to a seat belt anchor bracket. A seat belt passes through an opening in the bracket and is doubled back and sewn to form a loop. A magnet positioned on a sliding carriage is biased away from the sensor by springs. A seat belt loops around the carriage, and when tension is applied to the belt, the carriage with the magnet is drawn against the springs toward the GMR sensor. The GMR sensor measures the magnetic field present at the sensor and a microprocessor determines belt tension based on the known spring constants and the strength of measured magnetic field which is correlated with displacement of the magnet.

An electro-mechanical accelerometer is disclosed for use in a vehicle to selectively actuate a vehicular safety device such as, for example, an airbag when a deceleration force greater than a predetermined threshold level is sensed.
