Stop light switch/29 style

[coatings03]

A question for the forum: I'm currently building a 29 speedster I have experienced an odd occurrence. I mounted the stoplight switch on the shifting tower I hook up the attaching hook connecting the switch and brake peddle. I press down on the peddle and connecting rod protruding from the brake switch bends up and will not return into the switch. What is going on? This is the 3rd switch. Any help is appreciated
