What is a BiStable Switch?
Technically speaking, a BiStable Switch is a mechanical device which
offers two stable end positions with a single actuation.
However, complex mechanical devices usually defy explanation so an example of
a BiStable Switch can be found on
standard mechanical pen.
Our goal in the ENSC 494 Micro-machining course was to design a BiStable
Switch that could be
fabricated as a micro-machined device.
Motivation for a BiStable Switch
BiStable Switches can be used as:
- a switch to control mirrors in optical circuits
- a transmission for micro mobiles
Currently these applications are solved via a monostable switch.
Monostable switches however have drawbacks such as:
- high power consumption
- need to dissipate heat
