Abstract

A switch signals changes in position and accelerations of its housing. The switch housing includes a movably mounted permanent magnet and at least one reed switch. The permanent magnet is suspended in the manner of a planar pendulum. The reed switch is disposed in the effective range of the magnetic field below the circle segment described by the pendulum. The longitudinal axis of the reed switch is oriented approximately in the direction of the pendulum oscillations.
