COLE HERSEE 75903 - 7590X Double Pole Switches Series

Cole Hersee Battery Selector Switches energize either or both of two batteries.
Master disconnect switches prevent tampering of theft when equipment is unattended.
Battery isolators prevent the battery with the higher charge from draining into the battery with the lower charge.
Battery-related accessories include remote battery jumper terminals, feed-through studs, lockout lever kits and face plates.
All products listed in this section can be found in Section J of the Cole Hersee D-275 CATALOG.

• Two positions: Off-On. For 6-36V DC systems.
• dpstDouble Pole, Single Throw. circuitry which describes a switch. Double Pole means that this switch controls two circuits. It's like having two switches in one switch body, except that the switching action is the same in both. Single Throw means that this switch has one On position. It's likely to be an On-Off switch - but it controls two independent circuits.: Will disconnect the batteryA collection of voltaic cells grouped together to provide higher voltage and/or higher current than a single cell. The battery is a common DC power source, especially for vehicles or equipment that is used remote from the domestic power supply.
• Emergency vehicles and utility vehicles often have dual battery systems because of added power demand. Such systems necessitate the use of a Battery Selector Switch or a Low Voltage Disconnect Switch. and the alternatorCommonly refers to the DC charging device on an engine. The alternator is actually a three-phase AC device producing AC which is then rectified by a diode bridge to create direct current. In selecting a Battery Isolator, it's important to match the type of isolator to the alternator. or generatorA machine with rotating parts that is capable of generating electrical power. In the narrow definition 'generator' refers to a DC machine and 'alternator' refers to an AC machine. Sometimes the term generator is used to refer to AC machines as well. fieldTypically refers to a magnetic field. Specifically used when discussing the rotating electromagnetic field associated with an alternator. By varying the field current, thus its strength, the output of the alternator may be controlled. circuit.
• Electrical ratings: Large studs: 1000A intermittentSome switches are designed for infrequent (or intermittent) use. Devices such as solenoids may need a cooling period before they should be re-actuated. Rating a switch for intermittent use typically allows it to operate at a higher current than might otherwise be recommended. See continuous. You can use a Continuous Duty Solenoid in place of an Intermittent Duty Solenoid, but it would have a shorter life expectancy compared to the purpose-built Intermittent Duty Solenoid. DO NOT use an Intermittent Duty Solenoid in place of a Continuous Duty Solenoid!. 15 seconds On, 5 minutes Off. 125A continuous (unless noted). Small studs: 20A continuous.
• Chrome-plated diecast lever.
• Plated steel case.
• Brass contactsA pair of devices that touch or come apart at the point where the switch throw makes or breaks the circuit. Silver contacts are common because of their low conductivity and low electrical resistance. Many Cole Hersee switches have silver contacts..
• Brass mounting stem 3/4" -16 thread 23/32" (18.3mm) long.
• Fits panels through 3/16" (4.8mm) thick.
• Two 3/8" -24 and two 10-32 studs.
