Explore rotary limit switches for equipment position and motion detection. Review actuator movement, mounting arrangement, contact ratings, and the operating environment.
Rotary limit switches respond to the rotation of a shaft rather than direct linear contact. Internal cams operate the electrical contacts at predetermined positions, allowing the switch to stop, reverse or signal equipment after a specified amount of movement.
Important selection factors include the required gear ratio, shaft rotation, number of cam positions, contact configuration, electrical ratings, mounting method, enclosure rating and operating environment. The switch must also be configured so the contact points correspond correctly with the equipment–s allowable range of travel.
Products are organized generically so rotary limit switches from different manufacturers can be compared within the same category and technical filters.
