The conic springs are still in place on the dome sheet. File:Topre Mounting Plate with Switches.JPG | Side view of the mounting plate (PCB removed) showing two switches with keycaps. File:Topre PCBs (back) - FR-4 Glass Epoxy and FR-2 Paper Phenol.JPG | Underside view of PCBs from two keyboards: glass epoxy type (green), and paper phenol type (brown) used in older keyboards. File:Topre PCBs (front) - FR-2 Paper Phenol and FR-4 Glass Epoxy.JPG | Contact side view. Paper phenol (left) and glass epoxy (right). File:Topre PCBs (front) - FR-4 Glass Epoxy and FR-2 Paper Phenol.JPG | Contact side view. Glass epoxy (above) and paper phenol (below). File:Topre Switch Housings - Standard (left) and Hi-Pro (right).jpg | Switch housings from a standard Topre switch (left) and a Hi-Pro style keyboard (right) with sliders removed from both. File:Topre Sliders - Hi-Pro (left) and Standard (right).jpg | Switch sliders from a Hi-Pro style keyboard (left) and a standard Topre switch (right). They appear to be the same height, but the base design is slightly different. File:Topre Springs - Switching and Spacebar.jpg | Springs from a switch (left) and spacebar (right). The switching spring plays an essential role in switch actuation. File:Topre Screws - Case, Ground, PCB type 1 and 2.jpg | Screws from a Topre keyboard. Left to right: case screw, grounding screw, PCB screw (type 1), PCB screw (type 2). File:Topre Short Throw - Keycaps.jpg | Comparison of caps from a [[Topre Short-throw|short-throw]] keyboard and a standard cap (far right). Note the more conventional stabiliser method used for modifiers on a short-throw keyboard. File:Topre Short Throw - Comparison.jpg | Switch housings and sliders (short-throw versions on the right). File:Topre Short Throw - Switch Housings Underside.jpg | Underside of short-throw switch housings.

File:Topre Short Throw - Mounting Plate Underside.jpg | Underside of mounting plate from a short-throw keyboard. File:Topre Short Throw - PCB.jpg | PCB from a short-throw keyboard. A standard-size spring at the top shows the size difference. File:Topre Short Throw - Screw Comparison.jpg | Short-throw PCB screw (left) and standard Topre PCB screw (type 2, right). File:Silent Topre - Comparison Housing and Slider.jpg | Switch housings and sliders from a [[Silent|silenced]] switch (left) and a standard switch (right). File:Silent Topre - Slider Comparison.jpg | Switch sliders from a [[Silent|silenced]] switch (left) and a standard switch (right). Note the foam o-ring on the silenced variant. The silenced variant's longer stem counters the reduced travel from the foam o-ring. Not all silenced switches have this adjustment. File:Silent Topre - Foam O-rings.jpg | Foam and plastic o-rings from a silenced switch. The plastic film faces the top of the keyboard and makes contact with the switch housing's ceiling. </gallery>
