5.4. Separate Source Test Plug
The 10 Position and the 14 Position Separate Source Test Plugs
isolate the external connections from the relay or equipment un-
der test. The test plug accepts all common size banana plugs,
ring wire connectors, spade lugs and has a through hole for
meter probe or wire connections.
This test plug provides quick circuit testing by fitting into the
stationary contact jaws of any Flexitest Type FT Case or Switch.
The L-shaped test blades assure quick, accurate alignment be-
tween the Test Plug and the stationary contact jaws. The blades
connect the relay inputs and outputs to a set of binding banana
posts on the top of the Test Plug. An insulated barrier along the
bottom of the blades isolates the relay circuits from external
connections. Test circuits can then be connected to these bind-
ing posts, which are staggered for easy accessibility.
Before inserting the Separate Source Test Plug into service,
all switchblades must be placed in the full open position. In a
Flexitest Type FT Case, the plug is inserted in the bottom switch
jaw with the binding posts up and in the top test switch jaw with
the binding posts down.
5.5. Flexitest test kit

case to hold your hand held meter, test plugs, patch cords,
