Hi-Tek lock is a provisional name for a latching-action variant of the Hi-Tek High Profile switch.

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.<ref name="DT-VC4152" /> 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.
