No the switches are all intergral in the housing. I answered a similar question awhile back, but I just had this thought. pull the housings off and see if you can just sand the contact points down. There is probably corrosion on the metal, and don´t worry about it flying apart when you take it off the handle bar they´re all screwed into place. take note, or a picture, of where the wires lie so you put them back in close to the original spot or it will be difficult to put the housing back on. hope this helps
