Abstract (en)
A signalling apparatus of the type including a switch member (8) biased from its signal-operating position by a breakable member (11) which upon breakage allows the switch to move to its signal operating position, is provided with a fulcrum element (6) on which said breakable member (11) bears, and which is so located that upon breakage of the breakable member (11) said element (6) remains in contact with the same broken portion (12) of the breakable member as the switch member, thereby both preventing ready access to the switch and allowing the switch member to move to its alarm-operating position by applying a pivotal force to said broken portion (12) of the breakable member (11) about the fulcrum element (6).
