1. An assembly for pushing an electrode into a glass melting vessel, comprising:
a frame;
a first shaft;
a first pusher actuator mounted to the frame and configured to translate the first shaft relative to the frame;
a first contact mechanism attached to the first shaft and configured to translate relative to the frame;
a master actuator operatively connected to the first pusher actuator such that operation of the master actuator causes operation of the first pusher actuator; and
a torque limiter operatively connected between the master actuator and the first pusher actuator, the torque limiter configured to disengage when a rotational force on the master actuator exceeds a predetermined amount.
