Rotary switches

17 August 2011 Switches, Relays & Keypads

Lorlin Electronics’ CKS and CKF rotary switch ranges are now available as standard with low axial play, smooth feel and damped indexing for the professional audio, broadcast and high-quality instrumentation applications.

The switch body is manufactured from UL VO compliant fire retardant material, has a 27,5 mm diameter with standard 30° spindle indexing and may be specified with either solder or printed circuit board terminals. Up to four poles are available per switch with a maximum 12 positions and shorting (make before break -30° indexing only) or non-shorting (break before make) contact options. An adjustable stop is provided to allow the number of positions in use to be restricted. Other special order options include 60° or 90° indexing, continuous spindle rotation and reinforcement ring, and a moulded fixed stop.

The CKS and CKF switches are available with silver, gold-flashed or gold-plated switching contacts. Spindles may be specified with full length flats. The components are rated at 150 mA @ 250 V a.c./d.c. with an operating life exceeding ten thousand cycles. Operating temperature is -30°C to +85°C and proof voltage is 1500 V a.c. (initial).
