ABSTRACT:
A microswitch which is electrostatically actuated, which has a first open position and a second closed position in which said switch closes at least a contact line (30); the microswitch comprisinga movable part (10) which has at least a first actuated portion (11) and a second contact portion (12), which are mechanically connected by means of at least a connection element (13);said contact line/s (30) being placed between said first and second portions; wherein in the rest position of the microswitch the actuated portion is at a first distance d1from the contact line and the contact portion is at a second distance d2from the contact line;wherein the operation of the microswitch is the following:the first actuated portion is actuated by at least an actuating electrode (20), andin response to said actuation and via the connection element (13) the second contact portion (12) is arranged to contact said contact line (30) reducing said second distance d2to zero.
