Abstract (en)
[origin: EP0817227A1] A casing (10) encloses a contact block (B). An exterior command head (11) can rotate to several positions about one axis (X1) to give a slot for a switch operator key (A) and to turn a roller transmission mechanism that rotates about a second axis (X2) in response to the key to displace a push button (15). When the electromagnet (E) is on, the core pulls down a sliding support (21) to which is clipped a movable piece (25) that has an operating ramp (26) attached. The slide moves to the right and blocks the push button is blocked by means of a boss on a sleeve which is fixed coaxially with the button and butts against a shoulder (19b) on a head within the roller.
