  • 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 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. SWITCH SPECIFICATIONS Switching Power Maximum 62.5 VA 
