ABSTRACT:
Described herein is a roller contact device wherein, upon moving a drive arm into a contact closing position, a pair of roller contacts are pressed across a pair of stationary contacts through a pair of bridge links and a pair of roller shafts by a pair of support shafts which are each forwardly pressed by a compression spring, thereby closing the contacts. In the event if there is a difference in height between the contacting surfaces of the two stationary contacts, the bridge links are inclined to hold the roller contacts securely in the contact closing positions.
