Every larger older
Tappan manufactured microwave had a pull up door handle latch.
Every Litton manufactured on had either a button on the top of the cabinet for the largest, or on the smaller models, a large pivoting push lever on the lower edge of the control console.
When Litton began making them for Sears, there was no latch buttons. The safety switches were all in the door pull to open design, as in most today, except Panasonic, and some smaller ovens.
