What are Topre switches?

Topre switches are electrostatic, capacitive keyboard switches that have the feel of a rubber dome keyboard with all the benefits of a mechanical switch such as more tactility, less noise, and a non-mushy bottom-out. They are available on a limited number of keyboards.

Why are Topre switches so good?

Topre switches are non-contact switches. They actuate via a special PCB that has capacitive-sensing capabilities. When you initially press a Topre switch, there is a spring on top of a rubber dome that compresses. At a certain level of compression, the PCB can sense that the switch has been actuated.

How does topre keyboard work?

They work based on the principle of capacitance, which means that keypresses are sensed electrically, without any physical circuit closure. This design helps eliminate key bounce and is often considered more reliable than other mechanical switch designs from an engineering standpoint.

What switches are similar to topre?

The closest switch to topre would be a high-quality rubber dome board.

How does pre-switch help with soft switching?

Pre-Switch offers an embedded AI that adapts in-system by predicting switch behavior with incomplete device information, such as temperature and tolerances. Pre-Switch guarantees accurate soft-switching and reduced EMI, at higher switching frequencies than ever before.

Which is the correct definition of the word switch?

to operate the switch of (an electric circuit) so as to connect, disconnect, or divert. to turn (an electric light or appliance) on or off in this way. to transfer (a railroad train or car) from one set of tracks to another by use of a switch; shunt. to change or exchange: to switch places.

Who are the founders of pre-switch Inc?

Pre-Switch, Inc. is a Silicon Valley power architecture company that develops embedded AI technology to solve complex timing problems associated with forced resonance soft-switching in power conversion. The company was founded by industry experts in power semiconductors,…

What’s the difference between non clicky switch and semi mechanical switch?

Switch designs without this extra audible feedback are described as “non-clicky.” Electrostatic capacitive switch: an alternative “semi-mechanical” switch that uses a rubber or plastic dome over a spiral-shaped spring that rests directly on the keyboard’s circuit board.
