ABSTRACT:
A load responsive switch actuator mechanism comprises a body of deformable material (e.g., an elastomeric material) which deforms under either compressive or tensile forces to actuate a switch. In one preferred embodiment the deformable material is in the form of a solid, generally cylindrical configuration which, when compressed, will expand in diameter to actuate a load responsive switch. In a second preferred embodiment the deformable material is in the form of a generally cylindrical tube which, when subjected to a tensile load, will decrease in diameter and actuate a load responsive switch.
