Variants
Waffle frame Type 1
Latticework switches of the classic design. A movable piece of wire follows the latching track in the slider.
Waffle frame Type 2
Latticework switches, but with a raised platform around the slider.[1] The latching track is moved to a retention arm; a protrusion from the slider engages the track in the arm, and the arm pivots about its base.
Flat top
Later design, with the switch fully enclosed instead of open-topped and hollow. The latch design is the same as the waffle frame Type 2. A large cutout in the top of the switch is provided to allow the arm to swing from side to side.
