Abstract: A safety switch assembly for an electrical appliance to prevent the appliance from being operated unless its door is fully closed and latched. The switch assembly includes a first switch activated by a pivoted lever and a second switch activated by a slidable block carried by the lever. The lever and the block are sequentially moved to switch-activating positions as the latch of the appliance moves to a fully latched position.

Abstract: A miniature snap action electrical switch has a member fixedly supported in the switch housing which serves both as a common terminal for the switch and a mount for the switch blade structure. The switch blade structure includes the switch blade and a pivotal cam, and the switch blade has an integral tongue between two arched legs connecting a bridging portion at one end and a contact portion at the other. The tongue mounts in a notch in one face of the combination member, and the pivotal cam has a cam edge which engages the combination member on its opposite face. The switch blade is connected with the pivotal cam at the end of such cam opposite to the cam edge and is tensioned when so assembled in a mounted free position for the switch.
