Key switches

Keys

— the key is an elongated pressure surface with two working positions. When the upper end of the key is pressed, the circuit closes and the electric current consumer is turned on, and when the lower end is pressed, the electrical circuit opens, instantly turning off the current consumer. Pushbutton switches are used to control current consumers that require a fixed contact/shutdown (lighting, ventilation, etc.). The key mechanism is distinguished by its simple design and high reliability.
