In an embodiment, the tensioning element is indirectly linked to a tensioning lever having a locating surface on which a locking pawl of the unlatching mechanism bears in the tensioned state of the tensioning element. The locating surface is curved in the direction of the locking pawl and is movably disposed relative to the tensioning lever.

Abstract: The present invention is directed to a switch device that includes an actuator guide coupled to the switch actuator plate. The perimeter wall of the guide is disposed within the back body member in a nesting arrangement such that the actuator guide is configured to slide within the back body member in a substantially linear motion between a non-switch actuating position and a switch actuating position.

A transmission mechanism is coupled to the actuator guide and configured to convert the linear motion of the actuator guide into a rotational movement when the switch actuator plate is depressed. A mechanical switch mechanism is configured to move between a first switch state and a second switch state in response to the rotational movement of the transmission mechanism.

Abstract: A safety switch is improved by the feature of staying in an open position in the event of breakage of a working rod or breakage or dropout of an operation portion and having a simple structure facilitating size reduction. Even if a rotary shaft is released from a supported state in an operation portion because an operating force of an operation or the number of operations of extracting an actuator from the operation portion exceeds a breakage tolerance, a working rod is permitted to move in an urging direction of a coil spring and is assuredly moved to the operation portion. Therefore, a switch can be assuredly set to an open position and, hence, the safety switch can achieve the safety improvement.
