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.
Claims20
A switch for signalling changes in position and acceleration of its housing, comprising:
- a switch housing;
- a permanent magnet movably mounted in said switch housing and being suspended in the manner of a planar pendulum for oscillatory movement about a pendulum axis in a pendulum plane;
- and
- a reed switch disposed in said switch housing below circle segment described by the pendulum in an effective range of the magnetic field of said permanent magnet, said reed switch having a longitudinal axis that is oriented approximately in the direction of the pendulum oscillations.
