Features

• Rotary actuator switches mount through 5/8 in. or 15/32 in. diameter holes; lock washers, keyed washers, and wire-lock hex mounting nuts secure the switch in the mounting hole.
• Rotary actuator switches mount through 15/32 in. diameter holes; lock washers, wire-lock hex nuts, and a locating pin on top of the housing prevent switch rotation.
• Straight-action actuators for linear drive; an ice-scraper ring cleans the actuator on each operation.
• Ball-bearing straight-action actuators for operation in any direction; an ice-scraper ring cleans the actuator on each operation.
• Roller straight-action actuators for cam and slide drives with approach angles not exceeding 20°; roller adjustable laterally in 45° increments; ice-scraper ring cleans the actuator on each operation.
• Rotary link lever actuators connect to a rotating lever via a threaded rod for positive drive; lever operable in both directions and laterally adjustable to any position through 360°; threaded rod pivots in two planes; no spring return — actuator motion controlled directly by the driving mechanism.
• Rotary roller lever actuators for cam and slide drives with approach angles exceeding 30°; spring-return mechanism available in clockwise and counterclockwise operating designs; laterally adjustable to any position through 360°; laminated phenolic roller.
• High-speed drive switches designed to withstand "hammer blow" type actuation as encountered in over-center locking mechanisms; interchangeable in size with standard Type 1EN1–6.
• Low-force operating switches use a special spring construction to reduce the normal 6 to 12 lb (26.7 to 53.4 N) operating force to 3 to 6 lb (13.3 to 26.7 N); interchangeable in size with standard 1EN1–6; low-force 600 Series EN operating force: 3 to 6 lb (13.3 to 26.7 N).
• Extended overtravel switches feature a longer plunger and bushing extending EN overtravel capability from the standard 0.250 in. to 0.860 in. (6.35 to 21.8 mm); longer bushing also allows additional adjustment of plunger position.
• High shock and vibration catalog Type 1EN75-R3 (M8805/65-001) is MIL-S-8805 qualified, including Class H high shock and vibration; other switches for high shock and vibration applications use the same plunger mechanism and internal switch design as 1EN75-R3 and are expected to meet the same requirements.
