Abstract
An electric safety switch (3) resetting device (1) for the car safety device (5) of elevators includes a switch (3) shaped as a box attached to the lower skirt (9) of the car frame, near the car safety blocks (11). A mobile upper tongue (13) is engaged with a car safety block triggering lever (15), which tongue (13) can trigger the switch (3) under the action of said triggering lever (15) and reset it in the opposite direction when operated by the maintenance operator. A connecting rod arrangement (29) hinged to the tongue (13) can be remotely actuated by the operator using an actuator (35) while standing at the landing opening near the arrested elevator car, to drive said tongue (13) to a position that will reset the switch (3).
