(b) Motor Mercury Interrupters for Direct Current. a. d. 



We supply the following Motor Interrupters for pressures of 16, 24, 32, 65, 110, 

 150 and 220 Volts and would ask that the voltage desired be stated when ordering. If 

 this is not given we supply the Interrupters for 110 volts. 



The price of all Interrupters is exclusive of the mercury necessary for charging.

In this Interrupter the mercury is successively centrifvigated during rotation, thus preventing 

 enmlsionising. In this manner a regular, certain contact is assured as well as great certainty in action, 

 and constant cleaning and recharging, necessary with other mercury interrupters, is but seldom required. 

 The number of interruptions can be regulated within wide limits.
