RSID OPTION: ROTARY SWITCH MODULES

• Rotary switches

• Current up to 2 A

• SPDT: Single pole, changeover switch in CCW position - 3 pins

• Sealing IP60

MODULES: RS ON/OFF SWITCH



RSI CHANGEOVER SWITCH





The position of each module is free.

RS and RSI rotary switches are housed in a standard 148, 149

module size 12.7 mm x 12.7 mm x 5.08 mm (0.5" x 0.5" x 0.2").

They have the same terminal styles as the assembled electrical

modules.



An assembly can comprise 1 or more switch modules.



Switch actuation is described as seen from the shaft end.

D: means actuation in maximum CCW position



The switch actuation travel is 25° with a total mechanical travel

of 300° ± 5° and electrical travel of electrical modules is 238°

± 10°.





RSID Single Pole CHANGEOVER





In full CCW position, the contact is made between 3 and 2 and

open between 3 and 1. Switch actuation (CW direction) reverses

these positions.
