The flat shape of on and off push-button switches accommodates the human hand or finger and allows them to be easily depressed or pushed. These switches are compact alternatives to bulky mechanical switches.
On and off push-button switches can be interconnected so that pushing one button causes the other button to be released. Color coded switches rule out the risk of erroneous operation. These switches remain depressed when they are pushed on, and pressing them again turns them off, switching off their connected circuits. Illuminated on and off push-button switches are useful for home installation and can be easily located in the dark or at night.
