1. An apparatus (40,122) for controllably actuating a switch (42,124) mounted on a support frame (12,112) in response to a load being applied to a seat assembly (10,110) comprising:

  • actuator means (44,56,126,138,140,160) operatively associated with said seat assembly (10,110) and said switch (42,124) for sensing elevational movement of said seat assembly (10,110) relative to said support frame (12,112) and applying an actuating force to said switch (42,124) of a magnitude less than the load applied to said seat assembly (10,110), and for limiting the magnitude of force applied to said switch (42,124) to a preselected maximum value which is substantially less than the load being applied to said seat assembly (10,110);

    said actuator means (44,56,126,138,140,160) includes an actuator spring (44,126) having a first end portion (46,128) and a second end portion (48,130), said first end portion (46,130) being contactable with said switch (42,124) and forceably engageable therewith in response to movement of the seat assembly (10,110) towards said support frame (12,112).
