Push button change of the doorbell of the entrance

I was looking for a reason why the doorbell of the entrance did not ring, but it was not the main body of the doorbell and it was a poor contact of this push button. In the operation with a minute current, such a failure certainly occurs. Impressing that the exact same type name as 15 years ago was still inexpensive and sold!
