Rotary Switches - Series 25
OVERVIEW
Integral Series 25 Professional grade Rotary Switches are ideally suited for use in Industrial and Laboratory equipments. Double wiping self cleaning contacts and choice of excellent dielectric materials and suitable plating finishes result in long term reliability and consistent quality. An almost infinite variety of switching configuration meet most of the design requirements of the user. Assembly options are possible with the use of spacers, shields, etc. and permit custom built switches. 'O' ring sealing is available for both spindle and panel mounting bush. The balanced pressure indexing mechanism provided by 2 balls housed in a steel base provides smooth positive action with consistent and repeatable torque.
Switches type equivalent to JSS 51207 available.
FEATURES:
» Choice of 30, 45 and 90 deg. indexing angles.
» Make before Break, Break before Make or special rotor segments.
» Insulated shafts for RF circuits.
» Concentric shafts for operating a pot meter mounted t the rear of the switch.
» (on request).
» Rigid or flexible Tag PCB terminals (for single wafer only).
» Shields between wafers as per customer requirements.
» Gold plating on clips/rotor available.
» Dust proof caps to protect contact from dust available.
» Type approved to JSS 51207 available (with coin silver clips and panel and spindle seal).
