An electric switch push-button has two holding positions. One of the positions is for the switch open and the other for the switch closed states. The push-button has a head and body (5). The body (5) slides in a ring (9) when the head is pressed. The ring (9) has a pin (12) which slides in a specially shaped groove (11) of the body (5). The ring (9) can rotate about the centre-line of the push-button. A spring (7) restrains movement. When in the out position, the pin (12) is at the bottom V of the groove. When in the in position, the pin (12) is at the top V of the groove (11).
