Abstract
A pendant switch assembly for controlling a hoist, includes a transmitter mounted to a housing for wireless transmission of control signals to a receiver mounted remotely with respect to the housing and operatively connected to a power controller of a drive of the hoist. A plurality of control elements is arranged in the housing and actuated by a plurality of actuators from outside for delivering control signals for the power controller to the transmitter. Secured to the hoist is a traction member which is guided downwards, with a receptacle secured to a lower end of the traction member. The housing is securely attachable to the receptacle by plugging in the housing into the receptacle, and detachable from the receptacle by withdrawal thereof. Electric energy is supplied to the control elements and the transmitter by a power source which is also accommodated in the housing.
