LOUDSPEAKER PLUGS

SERIES 187

The 187 series 1/4" phone plugs are similar to the Switchcraft^® 184 plugs, except that they offer an attractive tapered handle with a snap-in flex relief. Other features include:

* Larger tip terminal to accommodate wire sizes up to 14 AWG.

* Choice of Satin nickel or black finish.

* Black flex relief bushing can be specified in three different cable diameter openings for maximum reliability of cable.

* Plug is rated at 15A rms (maximum) for use with audio loudspeaker applications.

SPECIFICATIONS

Sleeve, Tip and Body: Nickel-plated copper alloy. 

Terminals: Solder lugs: tinned copper alloy; Screw: tin-plated.

Handles: Die-cast zinc. Satin nickel or black finish.

Cable Relief Bushing: Black (thermoplastic elastomer).

SERIES 188 AND 299 PLUGS

* Switchcraft's 188 is more heavy-duty than our competitor's biggest 1/4" commercial phone plugs.

* Large curved tip solder terminal makes it easier to solder to heavy gauge wires.

* Longer sleeve terminal allows more room to make sleeve solder connections.

* Extra-large cable clamp securely grips cable of up to .450" in diameter.

* Will easily accommodate some varieties of four conductor 14 gauge wire and parallel two conductor 12 gauge wire.

* Bendable tab on sleeve terminal makes termination easier by holding down cable while soldering. In addition, such mechanical retention makes for a superior solder connection.

* Will handle up to 15 A. rms (maximum).
