A pushbutton provides an operator with a replaceable cam ring that converts the operating mode of the operator from push-pull to twist-to-release.

Pushbutton with replaceable mode cam

In certain embodiments, a system includes a mechanical actuator having a first member configured to engage a contact block to move a contact slide for a first distance between open and closed positions of an electrical contact pair. The mechanical actuator also has a second member configured to engage an auxiliary device to move an actuator for a second distance between first and second positions, wherein the first and second distances are substantially different from one another.

Dual function reset operator for an electrical device

A removable latch assembly is provided to connect a contact block to an electrical switch operator in an industrial controller. The latch assembly comprises a housing having a spring disposed therein, to which a rotatable collar is mounted. A contact block may also be connected to the rear side of the housing. The collar, including a tab, is initially disposed in a first locked position to allow the latch assembly to be mounted onto a shaft of the operator. The collar may then be rotated to a second self-retained unlocked position that allows the user to pull the latch assembly away from the electrical switch. When this occurs, the spring automatically rotates the collar back to the locked position to permit the latch assembly to once again connect the contact block to the operator.

Removable latch assembly for an electrical switch

A switch assembly is provided that comprises a switch having a normally open contact and a normally closed contact which is electrically connected to the normally open contact and which is located either within the same housing as the normally open contact or a separate housing. The housing(s) may be mounted onto a latch assembly which, in turn, is mounted onto a switch operator, thereby closing the normally open contact. If the latch assembly becomes mechanically disengaged from the switch operator, thereby rendering the normally closed contact non-operational, the normally open contact will open, thereby opening the circuit to a machine performing a controlled function. The user, noticing the stoppage of operation, will then be alerted of a malfunction within the switch assembly.
