The photo below shows the construction of the membrane keyboard contact elements. It uses three membranes, folded in the form of a sandwich: two of them, the top and bottom, are marked with silver-plated contact pads and conductors, and the third is the separating one, located between the two metallized and it has holes in the locations of the sites. Molded rubber bands act as key springs.Конструкция пленочной клавиатуры LPOS-084

 5 key positions
The key is removed in any position
2 keys included
A reliable metal mechanism

Electromechanical key working is rather simple:

- In mode 1 – last left position means that keyboard off and not sense on keys pressing, other positions mean activation different layers of layout;

- In mode 2 – each turn of key generates early programmed string like a keypressing

Features of keyboards with an electromechanical key:

- Only in the version of the keyboard with the interface PS / 2 so far;

- there is no external PS / 2 port for a standard keyboard;

The mechanical key functioning is quite simple: the leftmost position - the keyboard is disabled and does not respond to keystrokes; other positions - the activation of different layout levels.
Thus, the groups of keys assigned to the corresponding user are programmed into different levels, for example, the 0th level is for the cashier, the first level is for the administrator, 2 for the super administrator, and so on.
