  • the resilient clips 33 are in such a position in the shell 12 that, when the shell is positioned in the box 13 to be secured thereto by 3 the screws 19, the clips 33 will readily move into engagement with the contact fingers 34, as best seen in Fig. 3.
  • the electrical cord 26 forms a unitary part of the combined switch and connector block 12 which is formed of suitable insulating material.
  • the combined switch and connector block 12 can readily be removed from the casing 11 by simply loosening and removing the screws 19.
  • the resilient clips 33 automatically move out of engagement with the contact fingers or pins 34.
  • the resilient clips 33 automatically move into engagement with the pins 34 when the shell 12 is positioned in the box 13 preparatory to fastening the shell in position by the fastening screws 19.
