MC772 – Arm/Safe Switch_2.1
– A solenoid-operated rotary switch with detents so that, if a pulse of power is delivered to the solenoid, the switch will step from SAFE to ARM or from ARM to SAFE. The solenoid operates through an axial air gap. The axial force is translated to rotational motion by balls which ride in grooves in an inclined plane. A drum attached to the rotary switch, which indicates the ARM or SAFE condition, can be observed through windows in the side of the housing. There is an auxiliary lever at the end of the switch assembly which will allow manual movement of the switch from the ARM to the SAFE position, but not vice versa._2.5
