  4. Light switch - Wikipedia

    en.wikipedia.org/wiki/Light_switch

    A toggle light switch Internal components of a toggle switch. The toggle mechanism provides "snap-action" through the use of an "over-center" geometry. The design was patented in 1916 by William J. Newton and Morris Goldberg. [2] The switch actuator does not control the contacts directly, but through an intermediate arrangement of springs and ...

    IEC 60417-5007, [6] the power-on symbol (line), appearing on a button or one end of a toggle switch indicates that the control places the equipment into a fully powered state. (1 or | means on.) IEC 60417-5008, [7] the power-off symbol (circle) on a button or toggle, indicates that using the control will disconnect power to the device. (0 or ...

    The device usually acts as the interface of a sensor (such as a light curtain), designed to signal a safety-related event, typically when the light curtain beam's being "broken". OSSD signals are the outputs from the protective device (light curtain or scanner) to a safety relay .

  8. Toggle switch (widget) - Wikipedia

    en.wikipedia.org/wiki/Toggle_switch_(widget)

    A toggle switch is a graphical control element that allows the user to make a choice between two mutually exclusive states (such as on/off). Originally toggle switches were used primary in touchscreen-based user interfaces, but they have later become commonplace in desktop and web applications. Toggle switches have a similar function as ...

  9. Bistability - Wikipedia

    en.wikipedia.org/wiki/Bistability

    Light switch, a bistable mechanism. In a dynamical system, bistability means the system has two stable equilibrium states. [1] A bistable structure can be resting in either of two states. An example of a mechanical device which is bistable is a light switch. The switch lever is designed to rest in the "on" or "off" position, but not between the ...
