DEFINITION

Classification: 337/125

(under subclass 123) Subject matter including a normally open electrical circuit in series across the input and output terminals of the device and adapted when closed to complete an electrical circuit in parallel relationship with the thermal contact actuating means. For instance; the shunting or short circuiting means may comprise a switch arm operative by a relay armature operative when the potential applied across the relay winding exceeds a preselected value. The type of switching devices found here are most commonly used as Flashers.

(1) Note. Where the shunting or short circuiting device is for the purpose of voltage compensation the patent will be placed in subclass 124 above and officially cross referenced in this subclass.
