Body Systems

The operation is similar to any motor with a reverse circuit. The microswitch is mechanically positioned such as to operate when the roof is in a closed position. A microswitch is a miniature snap-action switch, that is actuated by very little physical force, through the use of a tipping-point or “over-center” mechanism. A rocker switch allows the driver to adjust the roof. A rocker switch is an on/off switch that rocks when pressed, which means one side of the switch is raised while the other side is depressed, much like a rocking horse rocks back and forth. It is mostly known from light activation. The switch provides the supply to the motor to run it in the chosen direction. The roof will be caused to open or tilt. When the switch is operated to close the roof, the motor is run.

A microswitch is a small sensitive mechanical switch usually fitted with a lever or actuator so that only a small force is required to operate a snap action switch. The actuator may be a simple lever or incorporate a roller as shown inFig. 2.10. The actuator causes contacts in the switch to open or close in various switch configurations from SPST to DPDT.
Interfacing

A microswitch is a simple electromechanical switch element which requires minimal operating and release force and which exhibits minimal differential travel. Microswitches are normally available in single-pole double-throw (SPDT) configurations and can thus be configured as either normally open (NO) or normally closed (NC).
Coupled mechanism and pull-in instability of several probe-membrane assemblies subjected to electrostatic force
Published in Mechanics of Advanced Materials and Structures, 2018
A conventional microswitch is assembled by two conducting electrodes, of which one is fixed and the other is movable. In the application of a voltage difference between the two electrodes, the movable electrode will deflect downward to the fixed electrode due to the electrostatic attraction. When Vdc is over the critical value, the electrical force overwhelms the restoring force and the pull-in instability happens. A microswitch is designed based on this critical phenomenon. The critical value of Vdc is called as the pull-in voltage Vpi[6]. In this study, one considers the coupled system composed of two movable electrodes: (1) a cantilever beam and (2) an elastic membrane. The pull-in voltage and displacement of the assembly are investigated.
