Rotary switches offer IP67 sealing

10 June 2009 Switches, Relays & Keypads

The new Lorlin CKS rotary switch family offers a cost-effective single wafer switch for a wide range of applications, including those requiring front-of-panel sealing to IP67.

The moulded body 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 restrict the number of positions in use. Other special order options available include 60° or 90° indexing, continuous spindle rotation, reinforcement ring and a fixed stop. Spindles may be specified with special flats, slots or knurls. No-bush and rear-drive versions are also available, as is sealed PCB termination.

The CKS family is rated at 150 mA at 250 V a.c./d.c. with an expected life exceeding 10 000 cycles. Operating temperature is -30°C to +85°C and proof voltage is 1500 V a.c. The switch body material is UL V0 rated with gold flashed or gold plated switching contacts.
