摘要： An operating head (11) for a safety switch (100) includes a key-operated cam mechanism (12) and a plunger (27) contacting the cam mechanism (12) and extending from the cam mechanism (12). In the safety switch (100), the plunger (27) is displaceable between first and second positions responsive to the cam mechanism (12). The safety switch (100) further includes at least one securing member (127) interacting with the plunger (27) and displaceable between a locked and a released position. When the securing member (127) is in the released position, movement of the plunger (27) is allowed. When the plunger (27) is in the second position, the securing member (127) is displaced from the released position to the locked position, which secures the plunger (27) in the second position.
