  actuated thermal element.

• May be used with natural, manufactured or mixed gases and with LP gases where

  means are provided for obtaining automatic pilot gas shut-off.

• Switch may be conveniently mounted in any position.

• Cover is easily removed, making switch terminals readily accessible.
