Abstract
A door latch mechanism which may be advantageously used for a door of electrical equipment such as a microwave oven, comprising a latch member on the door, catch means to engage the latch member when the door is closed, and resilient biasing means to bias the catch means into a position engaging the latch member. The catch means is moved into and out of the position to engage the latch member by means of a leverage linkage and the movement of the catch member into and out of the position to engage the latch member is transmitted to electric switch means through the leverage linkage. The door is opened only after the switch means has been made open.
