Claims

[Scope of utility model registration request]

A test consisting of a fixed contact mounted on an insulating base, and a movable contact made of a conductive leaf spring material, one end of which is fixed to the insulating base, and the other end of which approaches and separates from the fixed contact. In the contact mechanism, a tongue-shaped portion protruding from a side surface is provided at a longitudinally intermediate position of the movable contact,
During operation, the tip of the test button presses down on the tongue, so that the tip of the other end of the movable contact is tilted so that it can come into contact with a fixed contact formed by the lead wire of a resistor provided in the test circuit. A contact mechanism for testing an earth leakage breaker, characterized by the following configuration:
