Peco Rail Cleaner - abrasive rubber block

Rail Cleaner - The abrasive block is rubbed along the top surface of the rails to clean any dirt that will stop/disturb electrical connection of your model locomotives/ accessories (thus leading to poor operation) - IMPORTANT not to press too hard on the track (always better to take a few passes with the rubber than in one go) - Always be gently around point work whilst cleaning otherwise you could damage the point blades and tie-bar (switch mechanism) 

Peco Microswitch enclosed type

Microswitch enclosed type - Designed to fit into O Gauge points in the tie-bar housing  - The switch is designed to operate the polarity of electrofrog point work
