<p>An emergency transmitter comprises a housing in which a power source 17 and an emergency call generator 18 are arranged. The emergency call generator 18 may be connected to the power source 17 and thereby be energised to transmit an emergency call signal either by a hand switch assembly 22 or automatically by an inclination switch 24 associated to a delay circuit. The inclination switch 24 is a normally open contact which closes as soon as the housing deviates or is tilted out of its normal position. When closed, the inclination switch 24 energises without delay an acoustical generator 29 in order to announce the forthcoming actuation of the emergency call generator. <IMAGE></p> |
