To achieve a small-sized roller contact device having an increased capacity of current flow, the front and rear roller contacts 4a and 4b are arranged such that they face each other with the contact portions 1a and 2a of the first and second fixed contacts 1 and 2 therebetween to bridge-contact the contact portions 1a a and 2a of first and second fixed contacts 1 and 2 from the front and rear sides of the portions of the first and second fixed contacts 1 and 2 which are arranged in parallel to each other. The front and rear roller contacts 4a and 4b are supported by the front and rear roller contact supporting members 5a and 5b, respectively. The driving member 6 extends between the first and second fixed contacts 1 and 2 and supports the front and rear roller contact supporting members 5a and 5b. The springs are installed between the front and rear roller contact supporting members 5a and 5b.
