Illustration of Latch Placement and Alignment
The illustration depicts a side view of a cabinet door and frame. A rectangular cabinet door is shown, with a push-to-open latch mechanism installed near its edge. The latch consists of two parts: a receiver plate mounted flush to the inside of the cabinet frame and a corresponding actuator plate affixed to the inside of the cabinet door. The actuator plate is slightly recessed into the door, allowing for a flush surface. A small gap (approximately 1-2mm) is visible between the actuator and receiver plates when the door is closed, allowing for smooth operation. When the door is pushed, the actuator plate engages with the receiver plate, creating a secure closure. The illustration clearly shows the precise alignment necessary for the smooth operation of the latch mechanism; the actuator and receiver must be perfectly aligned to allow for effortless push-to-open functionality. Incorrect alignment can lead to difficulty opening the door or the latch failing to engage.
