Cole Hersee 24021 - 24021 - Intermittent Duty SPST Series

Cole Hersee intermittent and continous solenoids provide safe, dependable control of electrical systems on all type of DC low voltage vehicles. In addition, they are ideal for marine applications and for forward and reverse systems in golf carts, garden tractors, fork lift trucks and winch operation.
Solenoids are relays which are commonly used to remotely switch a heavier current. By using a solenoid, the amount of heavy wiring needed to power the load is reduced, since the control circuit mounted inside the cab typically utilizes a smaller wire gauge.
Housing are available in plated steel, phenolic or plasticized steel. A latching solenoid can act as a remote disconnect switch.

• 12V Grounded 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! duty with resistor shorting circuitA closed path (or loop) of electrically (or electromagnetically) connected components or devices that is capable of current flow. Typically consists of loads, sources, conductors, and circuit protection (circuit breakers and fuses). The path must be continuous and closed. .
• With a resistor shorting solenoidAn electromechanical device (or relay) that is used to switch large currents. It consists of a coil of wire and a moving contact that makes an electrical connection when the coil of wire is energized. Cole Hersee manufactures over 50 kinds of solenoid. See # 24059, stud 3 is Normally ope, and becomes common with 1 and 4 when the solenoid is energized. Commonly used in engine starting applications. Phenolic housing.
