A safety mounting device includes two movable members mounted within a housing, the second movable member being sandwiched between the first movable member and a stop member and the first movable member being biased against the second movable member. Both movable members are movable along the longitudinal axis of the housing with the second movable member also being capable of tilting with respect to that longitudinal axis and rotating with respect to that longitudinal axis. The engagement between the two movable members is of a cam surface-cam follower nature. Movement of the second movable member along the longitudinal axis towards the first movable member, rotation of the second movable member from its home position and tilting of the second movable member relative to the longitudinal axis all cause the first movable member to be displaced from its home position along the longitudinal axis. This displacement can be used to trigger a switch for control purposes.
