Switch: answer key, US style, sheet 2 of 2

  1. Fig. 1

    12

    Name Switch (SPST)

    A switch symbol stands for a contact that either completes or breaks a path.

  2. Fig. 2

    12

    Name Push button, normally open

    The momentary push buttons shown here change contact state while pressed and return to their drawn, unactuated state when released.

  3. Fig. 3

    12

    Name Push button, normally closed

    Switch contacts are drawn in their normal status: the position they rest in with no force applied. A normally-open (NO) contact is drawn open and a normally-closed (NC) contact closed; for a momentary push button, normal means not pressed.

  4. Fig. 4

    COM12

    Name Switch (SPDT)

    Poles count the separate circuits a switch controls; throws count the contact destinations available to each pole. An off position is not an additional throw.

  5. Fig. 5

    COM11A1BCOM22A2B

    Name Switch (DPDT)

    Poles count the separate circuits a switch controls; throws count the contact destinations available to each pole. An off position is not an additional throw.
